      We use signature object for type safety and additional validation, but the printing rules
      are questionable in some cases. Python type hints advocate the usage of `None` instead of its
      type, but printing a signature would insert NoneType (specifically replacing
      Optional[Union[...]] with Union[..., None] and printing it as Union[..., NoneType]).
      The NoneType doesn't exist as a `types` definition in some Pythons.
