The two myAction functions below seem to be equivalent and, for this small
case, show an interesting economy of code, but being far from a Haskell expert,
I have to ask, is the first function as small (code wise) as it could be?

import Control.Applicative
data Color
= Red
| Blue
| Green
| Yellow
| Orange
| Brown
| Black
| White
deriving (Show, Read, Eq, Enum, Ord, Bounded)
-- myAction :: IO Color
-- myAction = getLine
-- >>= \str -> return (read str :: Color)
myAction :: IO Color
myAction = read <$> getLine
