That's about what I would do in C. What's wrong with doing it that
way in Haskell? GHC should be smart enough to do pretty well
with those kinds of combinations.

If you do this sort of thing all the time and there are some combinators
that would make it more convenient for you - go ahead and make a
library out of them. And upload it to Hackage!

Regards.
