Well, anything's mutable at the C level -- the question is whether you *should* be mutating it. I think the datatype object should almost certainly be immutable. Since it's separated from the data it's describing, it's possible for one datatype object to describe multiple chunks of data. So you wouldn't want to mutate one in case it's being used for something else that you don't know about. -- 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
