OK, we can cover that in the documentation - if folks want to emulate
what happens during class construction after the fact, they'll need to

    cls.name = attr
    attr.__set_name__(cls, "name")

Semantically, I agree that approach makes sense - by default,
descriptors created outside a class body won't have a defined owning
class or attribute name, and if you want to give them one, you'll have
to do it explicitly.
