I'd find both of those to be scary options, since there can be many many different versions of the macros in the wild, making Python into a nightmarish hodge-podge of different dialects. But with support like this, Python could be more easily prototyped; a proposed new syntactic feature could be played with by coding it up as a macro, before it's actually part of the language. Users would be encouraged to try it but NOT to publish code using it. If some feature then became a part of (say) Python 3.14, then the macro system could be used to backport it as far as possible. So I'm +0.75 on this, but not with the justification you've given :) ChrisA _______________________________________________ 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/GEWCUFTCQJLTV2WF44BALX4CNJM2ZY46/ Code of Conduct: http://python.org/psf/codeofconduct/
