I would say yes we want that. It would be strange if you couldn't reset a variable explicitly to its default value. I don't expect people to do this often. But somebody might want to do a deep copy of an exception (with some systematic change), or there might be other reasons. I'm sure a few Python zen items apply here. :-) -- --Guido van Rossum (python.org/~guido) _______________________________________________ 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
