<pedant> Actually Python does use setjmp/longjmp somewhere in the
murky bowels of the interaction of readline and signals to generate
KeyboardInterrupt exceptions. </pedant> But you're basically right.
It struck me recently that most entrants to the obfuscated C
competition don't use setjmp/longjmp enough. I'd have thought you
could make something utterly incomprehensible with judicious use of
Unfortunately, nigh the whole world is now duped into thinking that
silly fill-in forms on web pages is the way to do user interfaces.
