An exception is even *worse* than a goto, since it's more powerful: It
jumps to a run-time-determined place, which can't necessarily be
determined by reading the source code.  And that place can be very far
away in the program (whereas a goto is local to a single subprogram).

Nonetheless, it's good to use exceptions when appropriate.

(It's interesting, though, that we're having a huge discussion about
fine-tuning the rules-of-thumb about exactly when it is, and is not,
appropriate to use goto.  But I haven't seen any such discussion about
exceptions.)
