When I've used such things in the past, I usually had some idea which classes I was interested in targeting. I used a metaclass for doing the tracking, and either invoked it on individual classes, or used __metaclass__ = X to apply it (something like "class object(object): __metaclass__ = X" would do the try for new-style class that inherit from object directly). -Mike _______________________________________________ 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
