Add an extra generic parameter.

(Also, it shouldn't be Box; you'd want a bog-standard generic newtype for this, not an extra heap allocation.)

yeah, I picked Box mostly as a pedagogical instance of the identity functor that already exists in the stdlib - in the real world you'd definitely want `struct Identity<F>(F)` instead.
