Variant of alias for enum type cannot be used as Literal

[colinfang]

class Foo(Enum):
    A = 1

F = Foo

# works
x: Literal[Foo.A]
# name-defined error
y: Literal[F.A]

Is there a simple workaround here? I also tried F: Final = Foo which doesn't work either

This looks like a bug. I'm not sure if there's any general workaround right now.

This looks like a missing case in lookup_qualified(), this doesn't work either:

class Out:
    class In:
        ...
O = Out
z: O.In  # Same name not defined error

Interestingly, visit_member_expr() has an elif branch for this, so for example this works (on master):

f: Final = F.A
reveal_type(f)  # Revealed type is 'Literal[__main__.Foo.A]?'

Should be easy to fix.
