I don't see the similarity (from reading this: http://www.haskell.org/haskellwiki/Idiom_brackets). My suggestion is just a way of using layout to avoid parenthesis.
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 away. And yes, you are right that applicative style is very useful.
