Well, well - network time warp strikes again.  Yesterday, I posted a note
regarding this very topic, as a result of a reply to the above message, which
arrived before the above message.  If I had waited, I wouldn't have made my
posting at all.  Oh well.  I am still going to make my own modifications to
expr, if only as a learning experience, but unless I do something profoundly
better than Peter's version, I will not bother the net with my efforts.

Sorry about the (unnecessary) noise, folks.

Cheers,
