As others have noted, the leading dot to disambiguate between a name assignment and a value check is going to be a problem. I think it's also unnecessary because instead of case BLACK: blahblah() we can do case _: # look ma! BLACK is just "color"! BLACK = color # if you really want it bound to another name In other words, the PEP is currently building in two ways to do the same thing -- make a default case. One of those ways is going to be a pain; the other, once renamed to "else", will be perfect! :-) As a bonus, no special casing for leading dots. -- ~Ethan~ _______________________________________________ Python-Dev mailing list -- [email protected] To unsubscribe send an email to [email protected] https://mail.python.org/mailman3/lists/python-dev.python.org/ Message archived at https://mail.python.org/archives/list/[email protected]/message/CMA3U3CBIPONZPSPXWFCDZWNUZKIESPH/ Code of Conduct: http://python.org/psf/codeofconduct/
