Are you saying that if I eval { die MyExceptionClass->new(...) }; that the $@ variable will contain the instance of MyExceptionClass?

Exactly ;-) From perldoc die:

die() can also be called with a reference argument. If this happens to be trapped within an eval(), $@ contains the reference. This behavior permits a more elaborate exception handling implementation using objects that maintain arbitrary state about the nature of the exception. Such a scheme is sometimes preferable to matching particular string values of $@ using regular expressions.

Awesome.. I tried it and I like it!

Now I just wish that something like this:

catch (ThisClass $e) {...}
catch (ThatClass $e) {...}

was built into Perl!!

Exception::Class::TryCatch is one non-core approach.
