I am getting the following error when trying to do a show on a Ranges object :-

I have attached the test source also :-

    import Data.Ranges

    test = (ranges [

        range 32 33,

        range 34 35,

        range 37 39

        ])

    main :: IO ()

    main = do {

        putStrLn (show test)

        }
