Description:
------------
Php 5.2 raises a notice when i try to read an overloaded 
property using foreach construct.

The foreach works correctly, so I don't think the warning 
should be raised.
Otherwise the foreach should not work (as don't work reset, 
next, current and other array functions).

Thank you,
Denis


Reproduce code:
---------------
class a {

    private $myArr;

    public function __construct() {
        $this->myArr = array('1','2','3','4');
    }

    public function __get($p) {
         if($p == 'myArr') {
             return $this->myArr;
         }
    }

}

$myObj = new a();

foreach($myObj->myArr as $value) {
    echo "myValue: " . $value."\n";
}



Expected result:
----------------
myValue: 1
myValue: 2
myValue: 3
myValue: 4




Actual result:
--------------
Notice: Indirect modification of overloaded property a::
$myArr has no effect in /tmp/test.php on line 21
myValue: 1
myValue: 2
myValue: 3
myValue: 4
