I'm pretty new to Haskell... are you looking for a *better* way to write this, or is this an exercise in exploring alternatives for the sake of understanding?

I'm not seeing any of the proposed alternatives as being as clear as the lambda function, and I'd be surprised (in my ignorance) if any of them were more efficient.
