It doesn't really need to be fast. If you need performance out of
Exceptions, you're misusing the idiom.
The exceptions are slowish but that hardly justifies adding an extra
amount of overhead on top of that. This might as well push people to
avoid them even where it makes perfect sense to use exceptions.
That being said let's see that beast and then measure, then optimize and
then judge it.
