- runClosure :: forall x. p (x -> a) (x -> b)
- close :: Closed p => (p :-> q) -> p :-> Closure q
- unclose :: Profunctor q => (p :-> Closure q) -> p :-> q

- curry' :: Closed p => p (a, b) c -> p a (b -> c)
Documentation
class Profunctor p => Closed p where
A strong profunctor allows the monoidal structure to pass through.
A closed profunctor allows the closed structure to pass through.
