Message216676
classmethod_descriptor instances such as vars(dict)['fromkeys'] are callable. The first argument has to be a subclass of __objclass__:
>>> vars(dict)['fromkeys'].__objclass__
<class 'dict'>
Calling the descriptor creates a bound built-in method; slices the args to remove the class; and calls it with the args and kwds.
>>> vars(dict)['fromkeys'](dict, 'abc')
{'a': None, 'b': None, 'c': None}

While the classmethod and staticmethod types that are defined in funcobject.c aren't callable, they do expose a __func__ member. |
