Agreed, but it's still a definition time bug, as the types are only nulling out tp_new after creating the singleton instance, and not preventing __new__ from resolving. If they *don't* null out tp_new, but instead set tp_new to a common helper function that raises "TypeError: Cannot create <type name> instances", that will both prevent __new__ from working, and also ensure that `type(obj)()` and `type(obj).__new__()` give the same error. (Changing the applicable version, as this issues combines a relatively obscure error reporting issue with a relatively intrusive fix, so the risk/reward ratio pushes it towards being a Python 3.8 only change). ---------- versions: -Python 3.7 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue34284> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
