One last question for the evening, I'm building the main input function of my Haskell program and I have to check for the args that are brought in

so I use

args <- getArgs
case length args of
    0 -> putStrLn "No Arguments, exiting"
    otherwise -> { other methods here}

Is there an intelligent way of setting up other methods, or is it in my best interest to write a function that the other case is thrown to within the main?

Or is there an even better solution to the issue of cases. I've just got to take in one name.

I'm trying to use Haskells Data.Heap module, but I'm incapable of even using it with integers. The only heap I've been capable of using is "empty", which does not take any arguments.
