Data.Bifunctor.Joker

Description

From the Functional Pearl "Clowns to the Left of me, Jokers to the Right: Dissecting Data Structures" by Conor McBride.

Synopsis

newtype Joker g a b = Joker {
- runJoker :: g b
}

Documentation

newtype Joker g a b Source #

Make a Functor over the second argument of a Bifunctor.

Mnemonic: Clowns to the left (parameter of the Bifunctor), jokers to the right.

Constructors

Joker
Fields runJoker :: g b
