It doesn’t make Python backward incompatible; it does mean that if typing or mypy relies on it, it becomes incompatible with earlier versions of Python (or has to fork different code for 3.8+ that relies on type.__or__ being available and 3.7- that doesn’t have whatever functionality relies on that). _______________________________________________ Python-ideas mailing list -- python-ideas@python.org To unsubscribe send an email to python-ideas-le...@python.org https://mail.python.org/mailman3/lists/python-ideas.python.org/ Message archived at https://mail.python.org/archives/list/python-ideas@python.org/message/TQ6HMT6X5XPKH6BCY4BLQYJJGFITZ43B/ Code of Conduct: http://python.org/psf/codeofconduct/
