Doesn't this really mean that in Py3, introspection APIs need a class *and*
an instance of that class for robust analysis of expected descriptor
results? (which was technically always true, the removal of unbound methods
just makes it significantly more important to handle descriptors with no
special behaviour on the class side of things).

And yes, I'm aware that idea poses a significant challenge for correct
handling of ABCs :P

Cheers,
Nick.
