Which kind of inheritance ? subtyping or implementation inheritance ?-)

FWIW, subtyping is implicit in dynamically typed languages, so they
don't need support for such a mechanism. And implementation inheritance
is not much more than a special case of composition/delegation, so it's
almost useless in a language that have a good support for delegation
(which we have in Python, thanks to __getattr__/__setattr__).
