[Haskell-beginners] How to access non-exported function from Data.Set?

Hi, In Data.Set there is a function splitLookup splitLookup :: Ord a => a -> Set a -> (Set a,Maybe a,Set a) that is not exported, but would precisely give me the functionality that I need. Not sure why it is not exported, but is there a way to use it?
