Well, since any existing code probably expects that behavior (or at least probably works if that is the case), I would be for such a change. I'm not sure what your policy is though. If there is recently written code that assumes the new types, are you OK with that breaking if it is changed back? I guess since it's an undocumented breaking change, it shouldn't be too much of an issue. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue39390> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
