That's why I called it a theoretical question and put theoretical in single 
quotes for an extra measure!

Sometimes I have musings about implementation details - especially if I'm 
having trouble with something in a real situation - where I start to ask myself 
"I wonder if they did it this way? Could it be done better this way?" etc., 
etc. Just musings that occupy my over active mind :-)

What prompted me to post this particular musing was that Lloyd's posting 
reminded me of this musing I had a couple of months ago, since everyone on the 
list was in SQL mode investigating Lloyd's question, I thought it apt to post.

However, I do appreciate your other - quite valid - points that I snipped out 
of this reply.
