Python2.6+ code parser

Question

Is there a parser that:

• is able to parse Python2.6+ code, and
• can be run in Python2.5 (python-only, no C extensions allowed)?

NOTE: This is somewhat related to my previous quostion about class decorators.

Answer 1

Yes, lib2to3 can, all you need to do is to provide it with the right Grammar file (get the source code for the Python you want and copy Grammar/Grammar).
