Re: Proposal: IntMap.differenceKeysSet for removing an IntSet of keys

If we had something like fromIntSet :: IntSet -> IntMap () then at least we could have a RULE to convert "difference m (fromIntSet s)" to "differenceIntSet m s". Then we could just hide differenceIntSet and the name wouldn't matter. Perhaps this "fromIntSet" function should be proposed as well? Cheers, -- Felipe.
