Josh Rosenberg <shadowranger+pyt...@gmail.com> added the comment:
If [].append == [].append is True in the "unique set of callbacks" scenario, that implies that it's perfectly fine to not call one of them when both are registered. But this means that only one list ends up getting updated, when you tried to register both for updates. That's definitely surprising, and not in a good way. ---------- nosy: +josh.r _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue1617161> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
