Well, you could cheat and reverse the test. ;-) I assume the problem is that loads proceeds to recreate the Fruit enum, rather than checking if there already is one? Maybe the metaclass can check somehow? At the very least, if this can't work in this implementation, unpickling should be an error. _______________________________________________ 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
