I have a generic type DLList which is a double linked list. As an inner
class there is Iterator. I find that the compile lets me use
DLList<Pair<K, V>>.Iterator as a type name in a declaration but not as a
type name in a cast. So

DLList<Pair<K, V>>.Iterator i = (DLList<Pair<K, V>>.Iterator)X.iterator();

fails because the cast syntax is not acceptable but then that means
that:

DLList<Pair<K, V>>.Iterator i = (DLList.Iterator)X.iterator() ;

fails because there is an unchecked assignment. A priori I would have
thought the same type names could be used in both places.
