Welcome to Haskell, where anything can be infix :-)

  That can be nice in a lot of situations. e.g. (+) 4 2 vs. (+) <$> Just 4 <*> Just 2 I usually prefer the applicative style above to liftA2 (+) (Just 4) (Just 2) because it preserves the "form" of the original expression and generalizes to more arguments. ie. it doesn't require liftAn for whatever n number of arguments my function takes.
