[Haskell-cafe] message passing style like in Haskell?

This is my second attempt to learn Haskell :)
Any way here's the code:
module Dot where
import Prelude hiding ( (.) )
(.) :: a -> (a -> b) -> b
a . f = f a
infixl 9 .
So for example, 99 questions: Problem 10
(*) Run-length encoding of a list.
encode xs = map (\x -> (length x,head x)) (group xs)
encode xs = xs.group.map token where token x = (x.length, x.head)
I found starting with data and working my way to a solution seems to be
easier to think with, or maybe it's just me ...
What is your thought?
