Hi Ethan,

Are you suggesting that inspect.get_mro(A) would return (A, object,
type)?  That seems very wrong to me.

If the goal is to fix `inspect.classify_class_attrs()`, then this
function only needs a specific fix, along the lines of looking in
`get_mro(A) + get_mro(type(A))`.  (A more minor issue is that the bug
report suggests `... + (type(A),)` only, but that's wrong: Python will
also look in all the base classes of type(A).)

"Fixing" inspect.get_mro() as suggested would break a lot of other usages of it.

A bientôt,
