Is there a justification for this somewhere?

I'm hoping someone will supply some. There seemed to be strong opinion on #haskell that this change should be made, but it might just have been a very vocal minority.

It true that (f $ g $ h $ x) might be nicer written (f . g . h $ x) but I've always thought the point of $ is for things like withSomeResource foo $ withSomeOtherThing bar $ yetAnotherBlockStructured thing $ ... Does that work? Or withSomeResource foo $ \x -> withSomeOtherThing bar $ \y -> yetAnotherBlockStructured thing $ \z -> Or does that case still work? There must have been some justification for the original design or was it just f $ g $ h $ x ? Duncan
