Feature or enhancement

Typeshed defines staticmethod and classmethod as generics:

  1. https://github.com/python/typeshed/blob/f6216ec6230aa51fe7e23afca30a8f5b18ace476/stdlib/builtins.pyi#L137
  2. https://github.com/python/typeshed/blob/f6216ec6230aa51fe7e23afca30a8f5b18ace476/stdlib/builtins.pyi#L154

It makes sense, because they are very callable-like. However:

>>> staticmethod[int]
Traceback (most recent call last):
  File "<python-input-0>", line 1, in <module>
    staticmethod[int]
    ~~~~~~~~~~~~^^^^^
TypeError: type 'staticmethod' is not subscriptable
>>> classmethod[int]
Traceback (most recent call last):
  File "<python-input-1>", line 1, in <module>
    classmethod[int]
    ~~~~~~~~~~~^^^^^
TypeError: type 'classmethod' is not subscriptable

We should consider making them generics in runtime as well.
