Depends on perspective. A goto can goto *anywhere* in the code. (almost) An
exception can only leap to certain well defined parts of the code with
rather specific purposes.

I can see your point - gotos have a single specific destination. (Unless you
have the Cobol "alter" statement at work for you.) Exceptions can goto a
variety of locations depending on context. My point was more from the static
usage perspective in that exception handlers can't appear just anywhere and
exceptions can't jump to just anywhere.
