I'm not quite sure I understand the use case for this -- we already have
a general catch/throw infrastructure, so this sounds like a somewhat odd
addition.

That is, currently you know what to look for when reading code that does
a throw, and this introduces a second thing to look for, and I'm not
sure that's a net win.
