But it's been answered already -- we can't change the meaning of StopIteration() with a value unequal to None, so it has to be a separate exception, and it should not derive from StopIteration.
How about having StopIteration be a subclass of the new exception? Then things that want to get generator return values only have one exception to catch, and things that only know about StopIteration will fail to catch the new exception. -- Greg _______________________________________________ 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
