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?
Michael 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
