I (too) often find myself writing code such as this:

if something   then putStrLn "howdy there!"   else if somethingElse           then putStrLn "howdy ho!"           else ...

[...]

So how do I make code like this prettier?

If it's a function, you can use guards:

foo :: ... foo something somethingElse    | something     -> putStrLn "howdy there!"    | somethingElse -> putStrLn "howdy ho!"    | otherwise     -> ...

Good idea, I hadn't thought of that... Currently this is all in the main function, checking the command line arguments. I suppose I could put it in a separate function. Thanks! -- Deniz Dogan
