Now they would behave differently.
I personally think they should continue to do the same thing, i.e. "in" should return True if there is a default; in the current proposal, it should invoke the default factory. But that's beside the point: Where is the real example where this difference would matter? (I'm not asking for a realistic example, I'm asking for a real one) Regards, Martin _______________________________________________ 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
