Whatver happened to Rod's work on the BETWEEN command? I remember he got to

The problem was that the optimizer wouldn't recognize it as an
optimizable/indexable case so it would be worse than what we have now,
and I don't think we wanted or could continue.

It got applied, some people reported failures, it was hastily backed
out, and no one seems to have followed up on it.

At this point I'd say it's not happening for 7.3 ...

I've not had time to implement the optimizer portion.
