Oh, AVY!

THANK YOU! I feel sure that is the answer to mav's
question that started this thread. (It's the one I'll take,
anyway, never mind the slings and arrows. And if anyone wants to quarrel with me on that score, I'll get cross.)

BUT--what I really want to thank you for is that second
link, the one from blockhead. That essay had me out of my
chair, going Yes! Yes! Yes!
