If you can live with f's domain being ordered, I'd probably use something
like f = lookupWithDefaultFM (listToFM list) (-1) importing FiniteMap from
ghc's libraries. HTH.

Use an array. Don't remember for sure, but I think something like
q = array (0, max (map fst list)) list
f = (q!!)
will probably work.
