[Haskell-cafe] Kleisli composition operator

I'm obviously missing something basic here but I don't seem to be able to use
the >=> operator which is apparently defined in the Prelude and also in

My imports are:

import Prelude hiding (abs, lookup, init)

import Data.Maybe
import Data.List as List hiding (lookup, insert, delete, union, init)
import Data.Map as Map hiding (update, delete, union, null, findIndex)
import qualified Data.Tree as Tree
import Control.Monad
import Control.Monad.State

Any suggestions anyone?
