Description
It would be nice to have a version of .when[Subclass] that throws instead of doing nothing when the focused element doesn't have the required type. I propose to name it .as[Subclass].

Research direction
Start by locating the existing .when[Subclass] implementation and its tests in the Quicklens repository. Compare its behavior when the focused element has the wrong type, then determine where a throwing .as[Subclass] variant should be covered. Done means the new operator throws on a type mismatch while preserving the matching case behavior.
