public abstract class AbstractReferenceSet<K> extends AbstractReferenceCollection<K> implements Cloneable, ReferenceSet<K>
Note that the type-specific Set interface adds a type-specific remove()
method, as it is no longer harmful for subclasses. Thus, concrete subclasses of this class
must implement remove() (the rem() implementation of this
class just delegates to remove()).

Iterable.iterator(), which was already
strengthened in the corresponding type-specific class,
but was weakened by the fact that this interface extends Collection.
