__getnewargs__ is not used by pickle protocol 0 and 1; to support those protocols we need __reduce_ex__. Since __reduce_ex__ works for 0, 1, 2, 3, 4, ... there's no reason to have both __reduce_ex__ *and* __getnewargs__. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue20653> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
