I (too) often find myself writing code such as this:
if something then putStrLn "howdy there!" else if somethingElse then putStrLn "howdy ho!" else ...
I recall reading some tutorial about how you can use the Maybe monad if your code starts looking like this, but as you can see, that doesn't really apply here. "something" and "somethingElse" are simply booleans and each of them have different actions to take if either of them is True.
So how do I make code like this prettier?
I'm not entirely sure if this is haskell'98, but GHC seems to support this sort of layout: main = do <some computation> if something then someOtherComputation else do <continue at the same indentation> <<<<< Antoine
