+-//
+-// less.js - parser
+-//
+-// A relatively straight-forward predictive parser.
+-// There is no tokenization/lexing stage, the input is parsed
+-// in one sweep.
+-//
+-// To make the parser fast enough to run in the browser, several
+-// optimization had to be made:
+-//
+-// - Matching and slicing on a huge input is often cause of slowdowns.
+-// The solution is to chunkify the input into smaller strings.
+-// The chunks are stored in the `chunks` var,
+-// `j` holds the current chunk index, and `current` holds
+-// the index of the current chunk in relation to `input`.
+-// This gives us an almost 4x speed-up.
+-//
+-// - In many cases, we don't need to match individual tokens;
+-// for example, if a value doesn't hold any variables, operations
+-// or dynamic references, the parser can effectively 'skip' it,
+-// treating it as a literal.
+-// An example would be '1px solid #000' - which evaluates to itself,
+-// we don't need to know what the individual components are.
+-// The drawback, of course is that you don't get the benefits of
+-// syntax-checking on the CSS. This gives us a 50% speed-up in the parser,
+-// and a smaller speed-up in the code-gen.
+-//
+-//
+-// Token matching is done with the `$` function, which either takes
+-// a terminal string or regexp, or a non-terminal function to call.
+-// It also takes care of moving all the indices forwards.
+-//

+-// less.js - parser
+-//
+-// A relatively straight-forward predictive parser.
+-// There is no tokenization/lexing stage, the input is parsed
+-// in one sweep.
+-//
+-// To make the parser fast enough to run in the browser, several
+-// optimization had to be made:
+-//
+-// - Matching and slicing on a huge input is often cause of slowdowns.
+-// The solution is to chunkify the input into smaller strings.
+-// The chunks are stored in the `chunks` var,
+-// `j` holds the current chunk index, and `current` holds
+-// the index of the current chunk in relation to `input`.
+-// This gives us an almost 4x speed-up.
+-//
+-// - In many cases, we don't need to match individual tokens;
+-// for example, if a value doesn't hold any variables, operations
+-// or dynamic references, the parser can effectively 'skip' it,
+-// treating it as a literal.
+-// An example would be '1px solid #000' - which evaluates to itself,
+-// we don't need to know what the individual components are.
+-// The drawback, of course is that you don't get the benefits of
+-// syntax-checking on the CSS. This gives us a 50% speed-up in the parser,
+-// and a smaller speed-up in the code-gen.
+-//
+-//
+-// Token matching is done with the `$` function, which either takes
+-// a terminal string or regexp, or a non-terminal function to call.
+-// It also takes care of moving all the indices forwards.

+-// less.js - parser
+-//
+-// A relatively straight-forward predictive parser.
+-// There is no tokenization/lexing stage, the input is parsed
+-// in one sweep.
+-//
+-// To make the parser fast enough to run in the browser, several
+-// optimization had to be made:
+-//
+-// - Matching and slicing on a huge input is often cause of slowdowns.
+-// The solution is to chunkify the input into smaller strings.
+-// The chunks are stored in the `chunks` var,
+-// `j` holds the current chunk index, and `current` holds
+-// the index of the current chunk in relation to `input`.
+-// This gives us an almost 4x speed-up.
+-//
+-// - In many cases, we don't need to match individual tokens;
+-// for example, if a value doesn't hold any variables, operations
+-// or dynamic references, the parser can effectively 'skip' it,
+-// treating it as a literal.
+-// An example would be '1px solid #000' - which evaluates to itself,
+-// we don't need to know what the individual components are.
+-// The drawback, of course is that you don't get the benefits of
+-// syntax-checking on the CSS. This gives us a 50% speed-up in the parser,
+-// and a smaller speed-up in the code-gen.
+-//
+-//
+-// Token matching is done with the `$` function, which either takes
+-// a terminal string or regexp, or a non-terminal function to call.
+-// It also takes care of moving all the indices forwards.

+-// less.js - parser
+-//
+-// A relatively straight-forward predictive parser.
+-// There is no tokenization/lexing stage, the input is parsed
+-// in one sweep.
+-//
+-// To make the parser fast enough to run in the browser, several
+-// optimization had to be made:
+-//
+-// - Matching and slicing on a huge input is often cause of slowdowns.
+-// The solution is to chunkify the input into smaller strings.
+-// The chunks are stored in the `chunks` var,
+-// `j` holds the current chunk index, and `current` holds
+-// the index of the current chunk in relation to `input`.
+-// This gives us an almost 4x speed-up.
+-//
+-// - In many cases, we don't need to match individual tokens;
+-// for example, if a value doesn't hold any variables, operations
+-// or dynamic references, the parser can effectively 'skip' it,
+-// treating it as a literal.
+-// An example would be '1px solid #000' - which evaluates to itself,
+-// we don't need to know what the individual components are.
+-// The drawback, of course is that you don't get the benefits of
+-// syntax-checking on the CSS. This gives us a 50% speed-up in the parser,
+-// and a smaller speed-up in the code-gen.
+-//
+-//
+-// Token matching is done with the `$` function, which either takes
+-// a terminal string or regexp, or a non-terminal function to call.
+-// It also takes care of moving all the indices forwards.

+- // Here in, the parsing rules/functions

+- // The basic structure of the syntax tree generated is as follows:
+- //
+- // Ruleset -> Rule -> Value -> Expression -> Entity
+- //
+- // Here's some LESS code:
+- //
+- // .class {
+- // color: #fff;
+- // border: 1px solid #000;
+- // width: @w + 4px;
+- // > .child {...}
+- // }
+- //
+- // And here's what the parse tree might look like:
+- //
+- // Ruleset (Selector '.class', [
+- // Rule ("color", Value ([Expression [Color #fff]]))
+- // Rule ("border", Value ([Expression [Dimension 1px][Keyword "solid"][Color #000]]))
+- // Rule ("width", Value ([Expression [Operation "+" [Variable "@w"][Dimension 4px]]]))
+- // Ruleset (Selector [Element '>', '.child'], [...])
+- // ])
+- //
+- // In general, most rules will try to parse a token with the `$()` function, and if the return
+- // value is truly, will return a new node, of the relevant type. Sometimes, we need to check
+- // first, before parsing, that's when we use `peek()`.

+- // rule, which represents `{ ... }`, the `ruleset` rule, and this `primary` rule,
+- // as represented by this simplified grammar:
+- //
+- // primary → (ruleset | rule)+
+- // ruleset → selector+ block

+-// less.js - parser
+-//
+-// A relatively straight-forward predictive parser.
+-// There is no tokenization/lexing stage, the input is parsed
+-// in one sweep.
+-//
+-// To make the parser fast enough to run in the browser, several
+-// optimization had to be made:
+-//
+-// - Matching and slicing on a huge input is often cause of slowdowns.
+-// The solution is to chunkify the input into smaller strings.
+-// The chunks are stored in the `chunks` var,
+-// `j` holds the current chunk index, and `current` holds
+-// the index of the current chunk in relation to `input`.
+-// This gives us an almost 4x speed-up.
+-//
+-// - In many cases, we don't need to match individual tokens;
+-// for example, if a value doesn't hold any variables, operations
+-// or dynamic references, the parser can effectively 'skip' it,
+-// treating it as a literal.
+-// An example would be '1px solid #000' - which evaluates to itself,
+-// we don't need to know what the individual components are.
+-// The drawback, of course is that you don't get the benefits of
+-// syntax-checking on the CSS. This gives us a 50% speed-up in the parser,
+-// and a smaller speed-up in the code-gen.
+-//
+-//
+-// Token matching is done with the `$` function, which either takes
+-// a terminal string or regexp, or a non-terminal function to call.
+-// It also takes care of moving all the indices forwards.

+-//
+-// less.js - parser
+-//
+-// A relatively straight-forward predictive parser.
+-// There is no tokenization/lexing stage, the input is parsed
+-// in one sweep.
+-//
+-// To make the parser fast enough to run in the browser, several
+-// optimization had to be made:
+-//
+-// - Matching and slicing on a huge input is often cause of slowdowns.
+-// The solution is to chunkify the input into smaller strings.
+-// The chunks are stored in the `chunks` var,
+-// `j` holds the current chunk index, and `current` holds
+-// the index of the current chunk in relation to `input`.
+-// This gives us an almost 4x speed-up.
+-//
+-// - In many cases, we don't need to match individual tokens;
+-// for example, if a value doesn't hold any variables, operations
+-// or dynamic references, the parser can effectively 'skip' it,
+-// treating it as a literal.
+-// An example would be '1px solid #000' - which evaluates to itself,
+-// we don't need to know what the individual components are.
+-// The drawback, of course is that you don't get the benefits of
+-// syntax-checking on the CSS. This gives us a 50% speed-up in the parser,
+-// and a smaller speed-up in the code-gen.
+-//
+-//
+-// Token matching is done with the `$` function, which either takes
+-// a terminal string or regexp, or a non-terminal function to call.
+-// It also takes care of moving all the indices forwards.

+-//
+-// less.js - parser
+-//
+-// A relatively straight-forward predictive parser.
+-// There is no tokenization/lexing stage, the input is parsed
+-// in one sweep.
+-//
+-// To make the parser fast enough to run in the browser, several
+-// optimization had to be made:
+-//
+-// - Matching and slicing on a huge input is often cause of slowdowns.
+-// The solution is to chunkify the input into smaller strings.
+-// The chunks are stored in the `chunks` var,
+-// `j` holds the current chunk index, and `current` holds
+-// the index of the current chunk in relation to `input`.
+-// This gives us an almost 4x speed-up.
+-//
+-// - In many cases, we don't need to match individual tokens;
+-// for example, if a value doesn't hold any variables, operations
+-// or dynamic references, the parser can effectively 'skip' it,
+-// treating it as a literal.
+-// An example would be '1px solid #000' - which evaluates to itself,
+-// we don't need to know what the individual components are.
+-// The drawback, of course is that you don't get the benefits of
+-// syntax-checking on the CSS. This gives us a 50% speed-up in the parser,
+-// and a smaller speed-up in the code-gen.
+-//
+-//
+-// Token matching is done with the `$` function, which either takes
+-// a terminal string or regexp, or a non-terminal function to call.
+-// It also takes care of moving all the indices forwards.

+-//
+-// less.js - parser
+-//
+-// A relatively straight-forward predictive parser.
+-// There is no tokenization/lexing stage, the input is parsed
+-// in one sweep.
+-//
+-// To make the parser fast enough to run in the browser, several
+-// optimization had to be made:
+-//
+-// - Matching and slicing on a huge input is often cause of slowdowns.
+-// The solution is to chunkify the input into smaller strings.
+-// The chunks are stored in the `chunks` var,
+-// `j` holds the current chunk index, and `current` holds
+-// the index of the current chunk in relation to `input`.
+-// This gives us an almost 4x speed-up.
+-//
+-// - In many cases, we don't need to match individual tokens;
+-// for example, if a value doesn't hold any variables, operations
+-// or dynamic references, the parser can effectively 'skip' it,
+-// treating it as a literal.
+-// An example would be '1px solid #000' - which evaluates to itself,
+-// we don't need to know what the individual components are.
+-// The drawback, of course is that you don't get the benefits of
+-// syntax-checking on the CSS. This gives us a 50% speed-up in the parser,
+-// and a smaller speed-up in the code-gen.
+-//
+-//
+-// Token matching is done with the `$` function, which either takes
+-// a terminal string or regexp, or a non-terminal function to call.
+-// It also takes care of moving all the indices forwards.

+-//
+-// less.js - parser
+-//
+-// A relatively straight-forward predictive parser.
+-// There is no tokenization/lexing stage, the input is parsed
+-// in one sweep.
+-//
+-// To make the parser fast enough to run in the browser, several
+-// optimization had to be made:
+-//
+-// - Matching and slicing on a huge input is often cause of slowdowns.
+-// The solution is to chunkify the input into smaller strings.
+-// The chunks are stored in the `chunks` var,
+-// `j` holds the current chunk index, and `current` holds
+-// the index of the current chunk in relation to `input`.
+-// This gives us an almost 4x speed-up.
+-//
+-// - In many cases, we don't need to match individual tokens;
+-// for example, if a value doesn't hold any variables, operations
+-// or dynamic references, the parser can effectively 'skip' it,
+-// treating it as a literal.
+-// An example would be '1px solid #000' - which evaluates to itself,
+-// we don't need to know what the individual components are.
+-// The drawback, of course is that you don't get the benefits of
+-// syntax-checking on the CSS. This gives us a 50% speed-up in the parser,
+-// and a smaller speed-up in the code-gen.
+-//
+-//
+-// Token matching is done with the `$` function, which either takes
+-// a terminal string or regexp, or a non-terminal function to call.
+-// It also takes care of moving all the indices forwards.

+-//
+-// less.js - parser
+-//
+-// A relatively straight-forward predictive parser.
+-// There is no tokenization/lexing stage, the input is parsed
+-// in one sweep.
+-//
+-// To make the parser fast enough to run in the browser, several
+-// optimization had to be made:
+-//
+-// - Matching and slicing on a huge input is often cause of slowdowns.
+-// The solution is to chunkify the input into smaller strings.
+-// The chunks are stored in the `chunks` var,
+-// `j` holds the current chunk index, and `current` holds
+-// the index of the current chunk in relation to `input`.
+-// This gives us an almost 4x speed-up.
+-//
+-// - In many cases, we don't need to match individual tokens;
+-// for example, if a value doesn't hold any variables, operations
+-// or dynamic references, the parser can effectively 'skip' it,
+-// treating it as a literal.
+-// An example would be '1px solid #000' - which evaluates to itself,
+-// we don't need to know what the individual components are.
+-// The drawback, of course is that you don't get the benefits of
+-// syntax-checking on the CSS. This gives us a 50% speed-up in the parser,
+-// and a smaller speed-up in the code-gen.
+-//
+-//
+-// Token matching is done with the `$` function, which either takes
+-// a terminal string or regexp, or a non-terminal function to call.
+-// It also takes care of moving all the indices forwards.

+-//
+-// less.js - parser
+-//
+-// A relatively straight-forward predictive parser.
+-// There is no tokenization/lexing stage, the input is parsed
+-// in one sweep.
+-//
+-// To make the parser fast enough to run in the browser, several
+-// optimization had to be made:
+-//
+-// - Matching and slicing on a huge input is often cause of slowdowns.
+-// The solution is to chunkify the input into smaller strings.
+-// The chunks are stored in the `chunks` var,
+-// `j` holds the current chunk index, and `current` holds
+-// the index of the current chunk in relation to `input`.
+-// This gives us an almost 4x speed-up.
+-//
+-// - In many cases, we don't need to match individual tokens;
+-// for example, if a value doesn't hold any variables, operations
+-// or dynamic references, the parser can effectively 'skip' it,
+-// treating it as a literal.
+-// An example would be '1px solid #000' - which evaluates to itself,
+-// we don't need to know what the individual components are.
+-// The drawback, of course is that you don't get the benefits of
+-// syntax-checking on the CSS. This gives us a 50% speed-up in the parser,
+-// and a smaller speed-up in the code-gen.
+-//
+-//
+-// Token matching is done with the `$` function, which either takes
+-// a terminal string or regexp, or a non-terminal function to call.
+-// It also takes care of moving all the indices forwards.

+-//
+-// less.js - parser
+-//
+-// A relatively straight-forward predictive parser.
+-// There is no tokenization/lexing stage, the input is parsed
+-// in one sweep.
+-//
+-// To make the parser fast enough to run in the browser, several
+-// optimization had to be made:
+-//
+-// - Matching and slicing on a huge input is often cause of slowdowns.
+-// The solution is to chunkify the input into smaller strings.
+-// The chunks are stored in the `chunks` var,
+-// `j` holds the current chunk index, and `current` holds
+-// the index of the current chunk in relation to `input`.
+-// This gives us an almost 4x speed-up.
+-//
+-// - In many cases, we don't need to match individual tokens;
+-// for example, if a value doesn't hold any variables, operations
+-// or dynamic references, the parser can effectively 'skip' it,
+-// treating it as a literal.
+-// An example would be '1px solid #000' - which evaluates to itself,
+-// we don't need to know what the individual components are.
+-// The drawback, of course is that you don't get the benefits of
+-// syntax-checking on the CSS. This gives us a 50% speed-up in the parser,
+-// and a smaller speed-up in the code-gen.
+-//
+-//
+-// Token matching is done with the `$` function, which either takes
+-// a terminal string or regexp, or a non-terminal function to call.
+-// It also takes care of moving all the indices forwards.

+-// less.js - parser
+-//
+-// A relatively straight-forward predictive parser.
+-// There is no tokenization/lexing stage, the input is parsed
+-// in one sweep.
+-//
+-// To make the parser fast enough to run in the browser, several
+-// optimization had to be made:
+-//
+-// - Matching and slicing on a huge input is often cause of slowdowns.
+-// The solution is to chunkify the input into smaller strings.
+-// The chunks are stored in the `chunks` var,
+-// `j` holds the current chunk index, and `current` holds
+-// the index of the current chunk in relation to `input`.
+-// This gives us an almost 4x speed-up.
+-//
+-// - In many cases, we don't need to match individual tokens;
+-// for example, if a value doesn't hold any variables, operations
+-// or dynamic references, the parser can effectively 'skip' it,
+-// treating it as a literal.
+-// An example would be '1px solid #000' - which evaluates to itself,
+-// we don't need to know what the individual components are.
+-// The drawback, of course is that you don't get the benefits of
+-// syntax-checking on the CSS. This gives us a 50% speed-up in the parser,
+-// and a smaller speed-up in the code-gen.
+-//
+-//
+-// Token matching is done with the `$` function, which either takes
+-// a terminal string or regexp, or a non-terminal function to call.
+-// It also takes care of moving all the indices forwards.

+-//
+-// less.js - parser
+-//
+-// A relatively straight-forward predictive parser.
+-// There is no tokenization/lexing stage, the input is parsed
+-// in one sweep.
+-//
+-// To make the parser fast enough to run in the browser, several
+-// optimization had to be made:
+-//
+-// - Matching and slicing on a huge input is often cause of slowdowns.
+-// The solution is to chunkify the input into smaller strings.
+-// The chunks are stored in the `chunks` var,
+-// `j` holds the current chunk index, and `current` holds
+-// the index of the current chunk in relation to `input`.
+-// This gives us an almost 4x speed-up.
+-//
+-// - In many cases, we don't need to match individual tokens;
+-// for example, if a value doesn't hold any variables, operations
+-// or dynamic references, the parser can effectively 'skip' it,
+-// treating it as a literal.
+-// An example would be '1px solid #000' - which evaluates to itself,
+-// we don't need to know what the individual components are.
+-// The drawback, of course is that you don't get the benefits of
+-// syntax-checking on the CSS. This gives us a 50% speed-up in the parser,
+-// and a smaller speed-up in the code-gen.
+-//
+-//
+-// Token matching is done with the `$` function, which either takes
+-// a terminal string or regexp, or a non-terminal function to call.
+-// It also takes care of moving all the indices forwards.

+-// less.js - parser
+-//
+-// A relatively straight-forward predictive parser.
+-// There is no tokenization/lexing stage, the input is parsed
+-// in one sweep.
+-//
+-// To make the parser fast enough to run in the browser, several
+-// optimization had to be made:
+-//
+-// - Matching and slicing on a huge input is often cause of slowdowns.
+-// The solution is to chunkify the input into smaller strings.
+-// The chunks are stored in the `chunks` var,
+-// `j` holds the current chunk index, and `current` holds
+-// the index of the current chunk in relation to `input`.
+-// This gives us an almost 4x speed-up.
+-//
+-// - In many cases, we don't need to match individual tokens;
+-// for example, if a value doesn't hold any variables, operations
+-// or dynamic references, the parser can effectively 'skip' it,
+-// treating it as a literal.
+-// An example would be '1px solid #000' - which evaluates to itself,
+-// we don't need to know what the individual components are.
+-// The drawback, of course is that you don't get the benefits of
+-// syntax-checking on the CSS. This gives us a 50% speed-up in the parser,
+-// and a smaller speed-up in the code-gen.
+-//
+-//
+-// Token matching is done with the `$` function, which either takes
+-// a terminal string or regexp, or a non-terminal function to call.
+-// It also takes care of moving all the indices forwards.
