class
Profunctor (p :: Type -> Type -> Type)essence-of-live-coding LiveCoding Formally, the class Profunctor represents a profunctor from Hask -> Hask. Intuitively it is a bifunctor where the first argument is contravariant and the second argument is covariant. You can define a Profunctor by either defining dimap or by defining both lmap and rmap. If you supply dimap, you should ensure that:
dimap id id ≡ id
If you supply lmap and rmap, ensure:lmap id ≡ id rmap id ≡ id
If you supply both, you should also ensure:dimap f g ≡ lmap f . rmap g
These ensure by parametricity:dimap (f . g) (h . i) ≡ dimap g h . dimap f i lmap (f . g) ≡ lmap g . lmap f rmap (f . g) ≡ rmap f . rmap g
