Data.Bifunctor.Clown

Description

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

Synopsis

newtype Clown f a b = Clown {
- runClown :: f a
}

Documentation

newtype Clown f a b Source #

Make a Functor over the first argument of a Bifunctor.

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