__special__ methods are how Python currently defines built-in GFs, so perhaps __isinstance__ and __issubclass__ slots (and their __r*__ counterparts) should suffice. OTOH, the old PEP 246 (implemented by both PyProtocols and zope.interface) just uses __conform__ and __adapt__ and basically works the same way as an __isinstance__/__risinstance__ pair... _______________________________________________ Python-3000 mailing list Python-3000@python.org http://mail.python.org/mailman/listinfo/python-3000 Unsubscribe: http://mail.python.org/mailman/options/python-3000/archive%40mail-archive.com
