If $index is null, $newval is naturally pushed onto the end of the array as ArrayObject::append

On my php 5.3.5 installation, i discovered that value can be set by reference and not by copy ... depending the context..

so this is différent from what a regular array()

<?php

function set(&$x, &$a )
{
   
$x[] = $a;
}

$x = new ArrayObject();
$y = array();
$z = new ArrayObject();

$a =  array( 'foo' );
set($y,$a);
set($x,$a);
$z[]=$a;

$a = array( 'bar');

set($x,$a);
set($y,$a);
$z[]=$a;

print_r($x);
print_r($y);
print_r($z);
?>

// output
ArrayObject Object

    [storage:ArrayObject:private] => Array
        (
            [0] => Array
                (
