@michaelandrepearce I will try to maintain the generics too if possible
(not simple to fight with generics!) and about the cast it will be put already
by the JVM with a thing called "uncommon trap" because generics live only at
compile time and the JVM always prefers to be safer than sorry.

do you mean `PagedReferenceImpl extends
LinkedListImpl.Node<PagedReferenceImpl>`?
