You can do left to right function composition with (>>>) Given functions f, g , h, h >>> g >>> f is equivalent to f . g . h Its from Control.Category, so it generalizes to other things, but for functions specifically its left to right composition. ( theres also (<<<), which in this case is identical to (.) ) ( Also present in Control.Arrow . Why? I dont know this topic well enough to explain. My understanding is limited to what these operators mean in the specific of functions. Functions(->) are a type as well, so they can be instances of typeclasses. for example instance Functor ((->) r) where fmap = (.) )
