Product : Fedora 14
Version : 0.02
Release : 1.fc14

Summary : Safely and cleanly create closures via string eval
Description :
String eval is often used for dynamic code generation. For instance, Moose uses
it heavily, to generate inlined versions of accessors and constructors, which
speeds code up at runtime by a significant amount. String eval is not without
its issues however - it's difficult to control the scope it's used in (which
determines which variables are in scope inside the eval), and it can be quite
slow, especially if doing a large number of evals.
This module attempts to solve both of those problems. It provides an
eval_closure function, which evals a string in a clean environment, other than
a fixed list of specified variables. It also caches the result of the eval, so
that doing repeated evals of the same source, even with a different
environment, will be much faster (but note that the description is part of the
string to be evaled, so it must also be the same (or non-existent) if caching
is to work properly).
