Surely Raymond's suggestion also suffers from a similar race condition? for x in set: return x creates a set_iterator. If another thread modifies the original set after the set_iterator is created but before the return, you would get a mysterious and almost impossible to debug RuntimeError. -- Steven D'Aprano _______________________________________________ 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
