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.
