Oh, you mean exactly like PEP 572 used to advocate for? :) Can't say I'd be against that, although I'm not enamoured of the function-like syntax. But if you remove the function-like syntax and change the semantics, it isn't exactly Tim's proposal any more. :) ChrisA _______________________________________________ Python-ideas mailing list Python-ideas@python.org https://mail.python.org/mailman/listinfo/python-ideas Code of Conduct: http://python.org/psf/codeofconduct/
