title: How do I Unregister 'anonymous' event handler
body: <p>Say if I listen for an event:</p>
  
  <pre><code>Subject.NewEvent += delegate(object sender, NewEventArgs e)
  {
      //some code
  }); 
  </code></pre>
  
  <p>Now how do I un-register this event? Or just allow the memory to leak?</p>
