[Haskell-cafe] message passing style in Monad

[jinjing]

I found that as I can do

  xs.map(+1).sort

by redefine . to be

  a . f = f a
  infixl 9 .

I can also do

  readFile "readme.markdown" <.> lines <.> length

by making

  a <.> b = a .liftM b
  infixl 9 <.>

Kinda annoying, but the option is there.
