Hi Michael If you going to the trouble of constructing a sum type (obliged to be 2 parameter) expressly to play well with the favourite single parameter classes e.g. Functor/ Applicative / Monad [*], maybe it is worth considering new names for the type and its constructors relating to what the Applicative/Monad instances actually model.
