Intersection ( dry D1, list D2 ) -> dry


Return the dry derived by the intersection of the dries `D1' and `D2'.
The intersection is the dry of those elements that are elements in both dries. So `Intersection' removes (see `DryRemove') all elements from `D1' that are not in `D2'.
Note: `D2' may be a list that is not a proper dry, in which case `Dry' is silently applied to it.
