Thanks a lot for the pointer to that!  I think this little thread did
indeed prove to be a productive exercise.  As we dig out of Brian's
major foundational rework, seeing what others have done with this type
of problem, with the benefit of more understanding and patterns in our
head to think about it, will be very productive.

Similar, with the caveat Darren pointed out of immediate consumption.

Best regards, and thanks again for pitching in!
