Yes, you're right.  I spoke (typed) too fast.  On the other hand (and
I know you know this; I'm just filling in the details) if you
eventually catch those exceptions you're going to get unwinding, and
if you never catch those exceptions you're going to abort().

What's an "ordinal C++ throw-expression"?  Do you mean "ordinary?"
