It doesn't warn for that many of the unportable problems, but I'm not sure it can warn for them either. It's certainly helpful, just not very much. :) I think the biggest help was added in 2.6.2, and that's warning for old integer division. It will also warn for modules that aren't supported anymore, if I remember correctly, and that's often helpful. But it won't warn for real tricky problems, like binary vs text in strings, and I don't see how it can either. And, I just realized, it doesn't warn for you using cmp or __cmp__ either, and 2to3 won't fix that, so it should actually warn for it. -- Lennart Regebro: Python, Zope, Plone, Grok http://regebro.wordpress.com/ +33 661 58 14 64 _______________________________________________ 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
