[Haskell-cafe] A question about monad laws

Hi, I am trying to get a better understanding of the "monad laws" - right now, it seems too obvious and pointless. I had similar feelings about identity function when I first saw it but understood its use when I saw it in action. Could someone please help me get a better understanding of the necessity of monads complying with these laws? I think, examples of somethings stop working if the monad does not obey these laws will help me understand it better. Regards, Kashyap
