Sure. This is different fixers, and then script to run it could have a parameter for version. I'd expect though that a 2to6 first targets 2.6+, and possibly never end up supporting 2.5 at all. I do realize there still is 2.4 out in the wild, but fewer and fewer people need to support it, and the effort to support it is much higher. > String translation is also an open question.

Yeah, that can't be done automatically. There is no generic way to determine if a string should be binary, unicode or native. _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
