While both, instance-specific interfaces and multiple adaptation, are used in Zope 3 and considered very useful, their usefulness is not dependent on each other. The whole concept surely becomes more interesting with both in place, of course.

What the standard library is already doing doesn't need blessing, and neither is blessing needed for allowing advanced paradigms elsewhere, since they're already in place right now. -- Gustavo Niemeyer http://niemeyer.net _______________________________________________ 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
