Definitely use exceptions. I prefer Error.pm for this (sorry, Dave!),
which allows your handler to simply be:
sub handler {
return try {
...
} catch Exception::RetCode with {
my $E = shift;
return $E->{code};
} <other exceptions>
;
}
And then anywhere within your code you can go:
throw Exception::RetCode ( code => SERVER_ERROR );
Of course there's a bit of setup to do beyond that, which I intend to
rewrite the section of the guide to detail real soon now (tm).
