title: What does object @object mean
body: <p>I've been playing around with events and delegates and need to raise my event asynchronously, thus I've been using:</p>
  
  <pre><code>public event EventHandler OnHelloEvent;
  
  public void Raise()
  {
      IAsyncResult syncResult = OnHelloEvent.BeginInvoke(this, new EventArgs(), null, null)
  </code></pre>
  
  <p>In Intellisense, the last <code>null</code> is stated to be <code>object @object</code>. I haven't come across this before and can't seem to find any documentation for it.</p>
  
  <p>What does this mean? Is it useful?</p>
