One of the reasons that this PEP was born is because metaclasses are being used in ways that don't look natural to some, like generating interface instances out of a class statement, so this would add an interesting way to support these constructs. That doesn't look like a good reason, though, to kill the metaclass support that Python took so long to maturate. Otherwise, a new optional extension could be included as well: "Removing the 'class' statement". -- Gustavo Niemeyer http://niemeyer.net _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
