An applicative functor morphism is a polymorphic function, eta : forall a. A1 a -> A2 a between two applicative functors A1 and A2 that preserve pure and <*>:
eta (pure c) = pure c eta (f <*> x) = eta f <*> eta x
What do you guys call such a thing? My leading candidate is "idomatic transformation".
An applicative functor is a functor with some extra structure. Such a function is a natural transformation between the underlying functors that preserves the extra structure. So "applicative transformation" seems a logical name.
