Correct me if I'm wrong, but it seems like Ruby's 
catch/throw takes care of this "abuse" of 
exceptions. If you want a clean way to exit deep 
nesting, use catch/throw. If you have a true 
error condition, use an exception. Right?

Before reading this piece, I hadn't put together 
why it would make sense to support both 
mechanisms. If there are other angles of this 
topic, I'd be interested in hearing about them.
