Relative to some of the other open items I'm involved in, I consider
this a low priority, so I'm not working on it right now.  I would also
appreciate some guidance from those who are more involved in inheritance
and partitioning to determine the best behavior.  It could be argued
that the current behavior is correct, and also that there are several
other correct behaviors.
