I write a lot of ocaml code (for money, even!) and haven't touched haskell for about four years. I still find the haskell version here easier to read. I imagine what's tripping you up is the operator soup. Whilst ugly (one of the things that turned me off haskell) it is a lot easier to read once you are familiar with basic haskell typeclasses (applicative, functor etc). That said, the ocaml version could definitely be a lot nicer.
