get and set are not fixed: http://bugs.php.net/bug.php?id=39449

Reproduce code:
---------------
<?php
error_reporting(E_ALL | E_STRICT);

abstract class Property {
	
	protected $vars = array();
	
	public function &__get($Key)
	{
		if(array_key_exists($Key, $this->vars)){
			return $this->vars[$Key];
		}
	}
	
	public function __set($Key, $Value)
	{
		 $this->vars[$Key] = $Value;
	}
}

class Human extends Property {}
class Pet extends Property {}

$Pet = new Pet();
$Pet->Name = 'I am a pet';

$Human = new Human();
$Human->Mypet = $Pet;
$Human->Mypet->Options['HumanID'] = 1;

print_r($Human);
?>

Expected result:

    [vars:protected] => Array
        (
            [Mypet] => Pet Object

                    [vars:protected] => Array
                        (
                            [Name] => I am a pet
                        )
