Description:
------------
I try to use the following notation:
$object->property1->property2 = 'value';
when property1 and property2 are properties we access trow __get and __set methods.
calling __get with property1 return an object that defined __get and __set methods.
but there is a warning explaining the object doesn't support property references.


Reproduce code:
---------------
<?php
class CBaseClass {
   private $text = 'default';
   function __Get() {
      return $this->text;
   }
   function __Set($name, $value) {
      $this->text = $value;
   }
}
class CExtClass {
   private $baseObject;
   function __construct() {
      $this->baseObject = new CBaseClass();
   }
   function __Get() {
      return $this->baseObject;
   }
}
$extObject = new CExtClass();
echo $extObject->extProperty->baseProperty, '<br>';
$extObject->extProperty->baseProperty = 'new';
echo $extObject->extProperty->baseProperty, '<br>';
?>

Expected result:
----------------
default
new


Actual result:
--------------
default
