It would be nice if
Try::Tiny [^] <http://search.cpan.org/%7Edrolsky/Exception-Class-1.36/lib/Exception/Class.pm#___top>
If you are interested in adding try/catch/finally syntactic sugar to your code then I recommend you check out Try::Tiny<http://search.cpan.org/perldoc?Try%3A%3ATiny>. This is a great module that helps you ignore some of the weirdness with eval and $@.
was ammended with what I found at http://www.perlmonks.org/?node_id=998104

Because Exception::Class->caught() explicitly checks $@ for the exception object with Try::Tiny you simplify this to something like:
catch {
$e = $_;
if(UNIVERSAL::isa($e,'MyException')) {
warn $e->error, "\n";
...
}
}
