this means its much harder to have a mixin to change the behaviour of a property
instead of super(Mixin, self).prop = foo
the code is super(Mixin, type(self)).prop.__set__(self, foo)
which is way harder to understand
the attached file demonstrates the problem and has a proof of concept for an extended super allowing descriptor invocations
