title: using jQuery.guid
body: <p>Can I use the <code>jQuery.guid</code> for my own use? I have elements where I need a unique id attr so I just want to set it to <code>jQuery.guid++</code> like so:</p>
  
  <pre><code>var guid = jQuery.guid++;
  
  $('&lt;a href="#" id="a' + guid + '"&gt;link&lt;/a&gt;').appendTo('body');
  </code></pre>
  
  <p>Is this safe? Will it break any code or plugins?</p>
