Perhaps Exception should have a null C layout?

But I still call YAGNI on this use case until I hear a good reason why
you'd ever want to raise a 3rd party class and it's not (a) for
backwards compatibility reasons or (b) just as easy to raise another
class with this class instance as an attribute.
