[Haskell-beginners] How to convert a Data.Set to a Descending List?

[Sunil S Nandihalli]

Hello everybody,
 Is there a more efficient way to convert a Set to a descending list?
I was looking for a function similar to Set.toAscList something like
Set.toDecList . I feel first converting to a ascending list and then
reversing may be in-efficient given that I actually don't need all the
elements only a last couple of elements..

Thanks,
Sunil.
