Given that this was a direct reply to Steven's mail, and he explicitly said: > (4) Using sigils to over-ride the default is okay.

And that's also the stated goal of PEP 642, quoting: > This PEP takes the view that not requiring a marker prefix on value > lookups in match patterns results in a cure that is worse than the > disease: Python's first ever syntax-sensitive value lookup where you > can't transparently replace an attribute lookup with a local variable > lookup So, both PEP 642 and Steven agree that the problem exists, and explicit marker is a suitable means to address it. Then, deriving "rebuttal" and "-1" to PEP 642 from Steven's mail sounds a bit confusing. -- Best regards, Paul mailto:[email protected] _______________________________________________ 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/4GXMELBO6HCXCYWKPQAXOSSC6ZD7Y2ZV/ Code of Conduct: http://python.org/psf/codeofconduct/
