R. David Murray added the comment:
This is a duplidate of issue 5996. It is not clear if we are going to treat it
as a bug or a doc bug.

New submission from Kevin Shweh:
The only check that prevents instantiating abstract classes is in
object.__new__, but most built-in classes never actually call object.__new__.
That means you can do stuff like
import abc
class Foo(list, metaclass=abc.ABCMeta):
@abc.abstractmethod
