It's strange that function definition AND call to the same function must have "&" before them.

$arr = array();
$ref =& oras($arr['blah'], array());
$ref []= "via ref";
print_r($arr);

/* result
Array
(
    [blah] => Array
        (
            [0] => via ref
        )

)
*/

// perl like ||=
function &oras (&$v, $new) {
  $v or $v = $new;
  return $v;
}
