     I think this may be essentially what we need to solve the
     problem.  It's on my list of things to do, but I don't know when
     I'll get around to it.  If you decide to work on it, can you try
     to post a proposed design to the list before implementing?  I'm
     trying to keep the casefile design clean, so I'd like an
     opportunity to give feedback before any major changes to it are
     checked in.

Sure thing.    The casefile stuff is certainly something that I'd get
advice on before hacking it, since I've not fully understood it.

I assume that you'd not want to impose the penalty of an
additional pointer on the ccase struct ?  --- that would mean a lot of
extra memory for very large casefiles, when it wouldn't in general be
needed.  My idea was a "derived class" of struct ccase, but I've not yet
thought out the details carefully.
