A class object isn't an instance of itself, it's an instance of the 
Class (to be extact, 'type') class. Method dispatching will also 
traverse the base classes when refering to the class object, too:

     >>> class Master:
     ...     @classmethod
     ...     def func(cls):
     ...         return cls
     ...
     >>> class Sub(Master):
     ...     pass
     ...
     >>> type(Sub)
     <class 'type'>
     >>> Sub.func()
     <class '__main__.Sub'>
