Description:
------------
If I use __set magic method for arrays and try to update some field of array I see 
the old value. But, if I use the same scheme for ArrayObject I'll get the right 
result.

Test script:
---------------
<?
class t
{
	private $data = array();

	public function __get($name) {
		return $this->data[$name];
	}
	
	public function __set($name, $value) {
		$this->data[$name] = $value;
	}
}

// define test array
$array = array( 'view' => array('x' => 1, 'y' => 1) );

$t = new t();
$t->mas = $array;

// update field of array
$t->mas['view']['x'] = 1111;
echo $t->mas['view']['x'];

echo '<br>';

$t->mas2 = new ArrayObject($array);
$t->mas2['view']['x'] = 1111;
echo $t->mas2['view']['x'];

?>

Expected result:
----------------
1111
<br>
1111

Actual result:
--------------
1
<br>
1111
