> Fix annotation import in from_callable to support annotations on arbitrary (variadic) arguments.
> For example, in IOTypeHintsTest.test_from_callable, the annotation for args and kwargs should be:
> {code}
> *args: T
> **kwargs: str
> {code}
> and converted to this in from_callable:
> {code}
> Tuple[T, ...]
> Dict[str, str]
> {code}
