I'd much rather write that as

$name = defined $nickname
        ? $nickname
        : defined $salutation && defined $last_name
            ? "$salutation $last_name"
            : 'Guest';

In my opinion it's much more pretty readable (and pretty) ;)

MJD says you can't just make shit up and expect the computer to know what you mean, retardo! I run a Win32 PPM repository for perl 5.6x+5.8x. I take requests. ** The Third rule of perl club is a statement of fact: pod is sexy.
