mergeMaps :: Ord k => Map k a -> Map k b -> Map k (MergeResult a b)

diffMaps :: (Eq a, Ord k) => Map k a -> Map k a -> Map k (MergeResult a a)

matchMaps :: Ord k => Map k a -> Map k b -> Either (k, Either a b) (Map k (a, b))

Attempts to match the keys of the maps to produce a map from keys to pairs.
