Hi, 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 Control.Monad. 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? thanks, Roly Perera
