If you want more sugar, what about the list monad?

main = do args <- getArgs sequence_ $ do arg <- args n <- [1..3] return (putStrLn $ show n ++ ") " ++ arg)

Or, what about using ListT to combine it with IO, eliminating the need for two separate `do' blocks? main = (>> return ()) $ runListT $ do arg <- ListT getArgs n <- ListT $ return [1..3] liftIO $ putStrLn ((show n) ++ ") " ++ arg) Mike
