I guess I should make one more point.

9. CATCH error handlers are to catch program errors that I know
inevitably occur, but that I don't anticipate. People will use your code
in God only knows how many awful ways. I'm not omniscient. But, on the
other hand, I'm not lazy either. I check EVERY SINGLE ONE of my
parameters and I try to anticipate common errors and check for those.
Sometimes it is embarrassing how much code is error handling code in a
small program. Don't use CATCH error handlers because you are too lazy
to do any work. Even Coyote is not *that* depraved.

Cheers,

David
