The documentation does state: 

   these are used to allow user-defined classes to support iteration

although the rest of it only refers to objects.

It seems to me CPython is being a bit too picky here. Why should it care
if the method is a class method or an object method?

Anyway, that leaves the clever iterator trick out of No-Buzzword Python.
