Thanks a lot; I think I am starting to comprehend.
I suppose this is the modify you mean:

  modify :: (forall s. MVector s a -> ST s ()) -> Vector a -> Vector a

forall is a chapter of Haskell which I have not made it through,
but with a concrete example which I need, I should manage tomorrow.

Thanks again, to both responders.
