Indeed. I think that extending raise's syntax is a little easier on the eye,
but the advantage is small. Certainly giving threads a throw method would
function as well.
I was indeed hoping that signals and exceptions could be delivered the same way
via such a mechanism, which would also allow signals to be delivered to a
chosen thread.
