This is "exactly" the applicative style, where idiom brackets come from.
 Use Control.Applicative:

f <$> x a
  <*> y b
  <*> z c

You can use the identity functor to recover "plain old" function
application.  Idiom brackets abstract the <$> (fmap) and (<*>) operators

And yes, you are right that applicative style is very useful.
