How will definitionorder be set in the case where prepare doesn't return an OrderedDict? Or where a custom metaclass's new calls its superclass's new with a plain dict? (I just wrote some code that does that. :-)
In his patch, type_new tests to see if the dict passed in is an ordered dict (PyODict_Check). definition_order is only created and populated if it passes the test.
