> The above classes are used as return value wrappers, thus when converting return value annotations to type hints, the argument of these should be used as the hint.
> Example (this should pass but doesn't currently):
> {code}
>   def test_timestamped_value(self):
>     def timestamped(e: int) -> beam.window.TimestampedValue[int]:
>       return beam.window.TimestampedValue(e, 0)
>     with TestPipeline() as p:
>       pcoll = p | beam.Create([1, 2, 3]) | beam.Map(timestamped)
>       self.assertEqual(int, pcoll.element_type)
> {code}
