Nonlocal references

One level up

def f():
    x = 1
    def g():
        reveal_type(x)  # revealed: Unknown | Literal[1]

Two levels up

def f():
    x = 1
    def g():
        def h():
            reveal_type(x)  # revealed: Unknown | Literal[1]

Skips class scope

def f():
    x = 1

    class C:
        x = 2
        def g():
            reveal_type(x)  # revealed: Unknown | Literal[1]

Skips annotation-only assignment

def f():
    x = 1
    def g():
        # it's pretty weird to have an annotated assignment in a function where the
        # name is otherwise not defined; maybe should be an error?
        x: int
        def h():
            reveal_type(x)  # revealed: Unknown | Literal[1]
