title: __proto__ for IE9 or IE10
body: <p>Is there any possibility to change the <code>__proto__</code> property of an object in IE9 or IE10?
  Or is MS still not planning to include it in their JS engine?</p>
  
  <p>I need it in a very special situation where I need to change <code>__proto__</code> <em>after</em> the object is created.</p>
