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 = (.)

)
