How do I know all thrown exceptions of a function?

I thought about this, and I think it's the way it would have to go, but I
*really* don't like it.

For a start, you shouldn't ahve to declare anything if you guarantee that
nothing happens. Lack of declaration should be "nothing happens".

Argh! From a practical viewpoint, this is the way to do it, but from an
aesthetic viewpoint ...
