No, the point is that all this talk about type-space mm dispatch depends
on there *being* type space.  Since there is currently no inheritance to
speak of then there really is no typespace so all of this talk is moot,
unless Dan comes along and says that yes there will now be real
inheritance on the PMC level.  Whether or not that will cause problems
will remain to be seen.
