class-bucket is used for the efficient implementation of subtype? and
instance? checks.  If you add classes at runtime, you need to recompute
the decision matrix and fill in these values in all <class>es.  Stealing
the code from compile time should just work.

I see no deeper reason why make(<class>) is unavailable, except that
nobody got around doing it yet.  So play with it and let us know.
