The guarantee that 2to3 will convert your code does not exist.

Additionally to be more compatible with 3.x syntax, you have to enable
3.x features in python-2.6.  Use of those features will make your code
incompatible with python <= 2.5.

So you either have 2.x compatible code or 3.x compatible code not both
(even including the script).
