I don't particularly care much; the analogy with raise makes sense,
but the PEP carefully only calls it with 3 arguments, and since there
are no use cases outside the PEP, the simpler implementation
(requiring 3 arguments) makes more sense to me.

If you want to implement this part, feel free to make it the way you like!

I consider PEP 343 as accepted at this point as it ever will be;
additional tweaks will be found during implementation.
