Are you sure about that? My experiments suggest that it has
the same problem as __annotations__:

Type "help", "copyright", "credits" or "license" for more information.
>>> class C:
...  __slots__ = ['a', 'b']

>>> class E(D):

['a', 'b']

['c', 'd']

Guido said the same thing.  I did say "Slots", not "__slots__", though.  You'll find that your class D supports attributes "a", "b", "c", and "d", and that's the inheritance I was referring to.
