Steven D'Aprano added the comment: I agree that returning type(self) or self.__class__ (not sure which is better) is the right thing to do.
It might be possible to argue that the Python version is buggy, if the C version is treated as the reference implementation and the Python version has to duplicate that. Or if the documentation specifies the C version's behaviour. But if the precise behaviour is unspecified, or if the Python version is the reference implementation, its best to treat this as an enhancement rather than a bug fix and only apply it to 3.7. I'm not sure which is the right approach here. ---------- nosy: +steven.daprano _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue31222> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
