Data.FunArr

Conversion between arrow values and wrapped functions.

Documentation

class FunArr (~>) w | ~> -> w, w -> ~> where

Convert between an arrow value and a "wrapped function". The "arrow" doesn't really have to be an arrow. I'd appreciate ideas for names & uses.

Methods

toArr :: w (a -> b) -> a ~> b

Convert a w-wrapped function to an arrow value

($$) :: (a ~> b) -> w a -> w b

Apply an arrow to a w-wrapped value

Instances

FunArr (->) Id

FunArr DArrow DVal

(FunArr ar w, FunArr ar' w') => FunArr (::*:: ar ar') (:*: w w')
