Being more powerful doesn't make it worse.  One could argue that when
exceptions are only raised for error conditions, they are not nearly as
dangerous as a goto which is designed (or hacked) into the "normal" 
operation.

(Aside: the way some people code, the destination of an Ada goto _can_
be far away--in a 4,000 SLOC subprogram.)
