Yes, please submit it. > > Also, would this be a change that would be considered a backwards > incompatibility? In other words, would patches like this be allowed > in 2.6/3.1 or only in 2.7/3.2. While I don't see a problem in backporting it to maintence branches, I would personally only apply it to the current development branches. It doesn't seem to fix a "bug", just make a nice improvement. -- Regards, Benjamin _______________________________________________ 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
