$config->{$section}->{$option} = $defaults->{$section}->{$option}
            unless $config->{$section}->{$option};

I would throw the word exists (or defined) in there after the unless, just in case a user ever wants to specify a false value (e.g., a blank subject line is very rarely a good idea, but occasionally when sending mail to certain kinds of really old autoresponders that read commands from the subject line it can be desirable; there are also highly specialised cases for a blank From field).

Sanity? Oh, yeah, I've got all kinds of sanity. In fact, I've developed whole new kinds of sanity. Why, I've got so much sanity it's driving me crazy.
