And then I said - heh Dave, why not read this telephone-directory
sized pile of paper that Andy and you just spent months putting
together, and lo!, I'm an idiot, as I forgot that '|' is set addition, 
and '+' is array concatenation, so '-' and '|' are the complementary
operators.


Sorry, folks, it's been a week of late nights. I should have locked
away the keyboard a long time ago.
