Reproducer:

    def test_forward_type_references(self):
        def foo(a: 'Foo') -> 'Bar': pass

        class Foo: pass
        class Bar: pass

        get_type_hints(foo)


The above gives the following exception, rather than resolving the type:

/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/typing.py:1001: in get_type_hints
    value = _eval_type(value, globalns, localns)
/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/typing.py:260: in _eval_type
    return t._evaluate(globalns, localns)
/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/typing.py:464: in _evaluate
    eval(self.__forward_code__, globalns, localns),
_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ 

>   ???
E   NameError: name 'Foo' is not defined
