Even though it is a non-data descriptor? It seems to have a get instead of a call method. The problem is that pydoc just classifies it as a descriptor first and assumes name will be there.

Either way is fine.

My way solves the original problem and defines methoddescriptor as a non-data descriptor that isn't super. I think that matches what people expect when calling that inspect.ismethoddescriptor().

OTOH, if methoddescriptor is viewed as synonymous with non-data descriptor, then, technically a super object should return True and your fix will have to go inspect.isroutine().

Name your poison. Add a test case. Then fix it.
