Maybe.  But the interpreter is not terminating quite yet; state is
still fine since the exceptions have not reached the top of the stack
if you caught it.  But then "terminal" sounds destined to die, which
is not true either since that only occurs if you catch the exceptions;
"terminating" portrays that the plan is the termination but that it is
not definite.

OK, TerminatingException it is.

=)  I should become a pundit for being able to tell what is going to happen.

Yeah, and so did everyone else basically.  While Guido has his "let's
get all excited about a crazy idea, but then scale it back" mentality,
I guess I have the "let's change everything for the better, but then
realize other people actually use this language too".  =)
