Well, not really; exception handlers can always be implemented with
straight error codes and some ugly syntax. It's just more efficient, and
easier for both the compiler and the programmer to deal with, when the
language supports exceptions as a program construct. (That means more
than Ada's wimpy one-handler-per-function stuff.)
