Can't access ClassVars directly in the class body

[4atj]

This piece of code raises an exception KeyError: 'a'

from typing import ClassVar

class A:
    a: ClassVar[int] = 1
    b: ClassVar[int] = a

Changing a to A.a fixes the issue! But that's not a valid python code.

Hey thanks for reporting!

This is mostly a duplicate of #862 so I'll be closing this in favour of that. That issue also included one more bug, but it's been fixed so the same underlying issue (class-level scoping is broken) is the same as this one.
