Thanks for the reply, Alan.  But that is one handler that catches only one exception. What about exception_1 with handler_1, exception_2 with handler_2,...?  Does that have a flat structure or does it require nesting?

Could someone point me to some code examples of exception handling that are elegant?  All the examples I have come across, apart from the very simplest cases, look like a submission to an obfuscation contest.
