Please don't _ever_ advocate this programming style! Wrapping
something in a try/except that emits a generic message and terminates
is a bad idea - the default behaviour, if you simply let the exception
happen, is to emit a very useful message and terminate. Never test for
any error condition you're not prepared to handle, as the BOFH advised
his boss.
