That sounds bad for people who want to use a few choice keywords. (And I > think you'd be against that, for that very reason; as am I.)
Yes, that's exactly it! The analogy is with comma-separated items in the subscript, which get collected (bundled) into a tuple, rather than allocated to multiple parameters. And you are correct that I am against that. If people want that behavious for their class, they can use `**kwargs`. So I think we're on the same page here. -- Steven _______________________________________________ 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/JMVVORZHH7MJIYKEIVW3R4SJM3PEM7OM/ Code of Conduct: http://python.org/psf/codeofconduct/
