[Python-ideas] List the methods of a metaclass in the help of its instances

For example, in the help of ABCs, the register method witch is defined in ABCMeta is not listed. It's a little bit weird, since it's accessible from the class just like any classmethod or staticmethod, and it's a real feature of the class. I think it would be great if there was sections in the help that look like: | ---------------------------------------------------------------------- | Metaclass methods defined in <TheMetaclass>: | ---------------------------------------------------------------------- | Metaclass methods inherited from <TheMetaclassParent>: The same rules of visibility would apply of course.
