  1. neat. is this based on lib2to3 (did you just modify the grammar and add new rewriters, or is did you also implement new support code)? also, what’s the licence? thanks! andrew

  2. It uses lib2to3′s fixer mechanism as a dependency; the lib2to3 grammar is a hybrid of Python 2 and Python 3, so the primary work of lib3to2 is the new fixers/rewriters.

    It’s released under Apache License 2.0.

  3. sweet (also, thanks for the info on the 2to3 grammar, which actually means I don’t need this! :o )

  4. This is a very interesting concept. If I understand correctly what you mean, people could develop in Python 3 and use this tool to keep a Python 2 version in sync. I hope that helps speed up adoption of Python 3. Congratulations for your work!
