Nested class body can read out-of-scope bindings from parent class

[samwgoldman]

Describe the Bug

class A:
    a: int = 0

    class B:
        b = a # should fail, a is not in scope

At runtime this fails with a NameError. We seem to deal with the scope properly from nested def but not from the class body itself.

No longer repros I think? Sandbox now reports a type error for the provided example.
