The virtual field pattern

I was thinking that a practical use for this pattern would be, for
example, the Collections API, like java.util.List:
package java.util;
public interface VirtualList {
List getDelegateList();
boolean add( Object o ) default {
return getDelegateList().add( o );
}
...etc.
}
(Generics omitted for brevity.) Definitely not a package-private
interface. Nor would I personally guess that the more interesting uses
of the virtual field pattern would be "probably" package-private
either. I'd guess they're all public, myself.
