Yep. I tried exceptions with 2.7.0 (on a linux box) when I heard
it did support exceptions (and you *do* need those for errors
in constructors...). But when it spit back that message... I gave up.
Hoping for 2.8... hope it supports more (all?) of the upcoming
ANSI Std.

Thass right... the exception system is strangely similar to 
Common-Lisp's...

As I said... I don#t *use* the stuff. When they put an option into
a program that is not documented AND SHOULDN'T BE NECESSARY IN THE
FIRST PLACE... I don#t trust it. Simple. Very little trouble.

Oh, I will... BTW, how's tricks? Didn't get to check out your DJFC
yet... maybe today. Or did you get some more stuff done since you sent
it?
