Where `T` is an arbitrary type, if it is a subtype of the scrutinee's type `Scrut`, a [type test](../other-new-features/type-test.md) is performed before calling the method.
`U` follows rules described in [Fixed Arity Extractors](#fixed-arity-extractors) and [Variadic Extractors](#variadic-extractors).

**Note:** `U` can be the type of the extractor object.
