A problem with `(int, str)` that I believe hasn't been brought up yet is that it interferes with the existing use of subscription syntax, particularly by `Tuple`.
`Tuple[int, str]` is equivalent to `Tuple[(int, str)]` but not to `Tuple[Union[int, str]]`, because `__getitem__` receives a single tuple instead of multiple arguments. I think all other subscriptable types could resolve the ambiguity in principle because they aren't variadic. _______________________________________________ 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/J3VM5PEV6BX5DH36QFUJFOWNM5QPKNKU/ Code of Conduct: http://python.org/psf/codeofconduct/
