Maybe I annoy you with my distinction of errors and exceptions, but I consider DivideByZero a bad example for an exception, because it is more an error (I see it is used in the extensible exception paper anyway). A division by zero is not a problem that comes from the outside world like 'file does not exist'. In contrast to that, it's absolutely predictable: It occurs whenever you divide by zero. I'd thus call it a programming error.
