Reading The Fine Source it appears that variable is just used as the fallback fstab argument used IFF it's defined and the caller hasn't passed that key to the constructor. It doesn't look like it's explicitly populated. That being said it looks like you could be slightly naughty (in breaking encapsulation) and peek inside the object and pull it out with something like $foo->{fstab} after you have an instance.
