I kept close to your suggestion, but avoiding monads, especially IO, is a
good idea. If you do not need low-level memory access with peek and poke,
better use lists or arrays (high level) or StorableVector (more efficient
but not as flexible as array).
Avoiding explicit recursion is also a good thing - using too much (tail)
recursive function calls ends up looking like code with lots of GOTOs.
Better use higher order functions.
