I'm not sure what would have saved bacon in the above case. I don't see how
your example would work. I think it contained a typo.
In what I think you were trying to demonstrate, I would just pass $x by
reference (&$x) -- or -- return $x by value. I would not have used a global,
In any event, I seldom use globals anyway. This was more an academic discussion.
