    Sets are not in Python until 2.3, and rdata are not immutable so
    we cannot use sets.Set anyway.  This class implements subset of
    the 2.3 Set interface using a list as the container.

        There is a 'clone protocol' that subclasses of this class
        should use.  To make a copy, first call your super's _clone()
        method, and use the object returned as the new instance.  Then
        make shallow copies of the attributes defined in the subclass.

        This protocol allows us to write the set algorithms that
        return new instances (e.g. union) once, and keep using them in
        subclasses.
