abstract class Foo<SubClassOfFoo extends Foo<SubClassOfFoo>>
{
    /** subclasses are forced to return themselves from this method */
    public abstract SubClassOfFoo subclassAwareDeepCopy();
}

//to define methods whose argument types and return types are in
//terms of the subclass type, not the superclass type.
