title: Set_error_handler with static-method callback
body: <p>I <code>RTM</code> but I couldn't find any nice answer to this question, so here is it:</p>
  
  <ul>
  <li>Can I call a static
  method as an error handler (for example: <code>set_error_handler('error::function')</code>)?</li>
  <li>Is it recommended?</li>
  </ul>
