A coworker passed on the following bit of code, which, as far as I can tell, does nothing: 
$x ||= 0;

$x = -1; $x ||= 0; print $x;
-1
$x = 0; $x ||= 0; print $x;
0
$x = 2; $x ||= 0; print $x;
2
$x = 3; $x ||= 0; print $x;
3
$x = 123132; $x ||= 0; print $x;
123132

Any ideas on how or why something like Or, Or, Equals Zero would be used?
