This module contains useful functions to work with `Functor`

type class.

# Documentation

(<<$>>) :: (Functor f, Functor g) => (a -> b) -> f (g a) -> f (g b) infixl 4 Source #

Alias for `fmap . fmap`

. Convenient to work with two nested `Functor`

s.

`>>>`

Just [-1,-2,-3]`negate <<$>> Just [1,2,3]`
