        return new self;
    }
}

class Ext_One extends Base {
    public function __construct() {
        parent::__construct();
        echo __METHOD__ . "\n";
    }
}

class Ext_Two extends Base {
    public function __construct() {
        parent::__construct();
        echo __METHOD__ . "\n";
    }
}

$o1 = Ext_One::run();
$o2 = Ext_Two::run();
