Does that imply that in a frozendict, the *values* as well as the *keys* must be immutable? Isn't that a pretty strong limitation (and hence, does it not make frozendicts a lot less useful than they might otherwise be)? _______________________________________________ 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
