Yes, but this is an exceptional situation. We normally don't add new APIs in bugfix versions. We'll have to live with it. > 3. > [...] > Ugly, but perhaps crazy brilliant.

Besides, code written for 2.7.1 might not "blow up" with 2.7, but it will still have different behaviour. If you are using the new parameter, it's because you *need* it, hence different behaviour will be unacceptable; therefore, better to raise an error as the API change proposal does. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue2986> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
