The idea was that the classes you would actually use are arbitrary
combinations of "partial implementation" classes that bear no inheritance
relationships.
Seems like I misunderstood your problem and you were after the technical
means to perform this combination at runtime. - Michele has just shown how
to achieve that with type().
