The mechanism is class-agnostic. The only thing it relies on is that
it's an object of some class type.

Imposed interface to do what with the exception?
OK, so I can think of one example it would be nice to have: stack
traces. This could be implemented in Exception, I suppose. But still,
restricting throw to this class would be a puristic rather than
practical step forward.
