title: Is there any alternative way to access JavaScript globals that have been shadowed or redefined?
body: <p>For some unknown reason the name <code>URL</code> in my event handler points to a string value with the current URL of the browser instead of the constructor for an URL object. Trying to call it results in the following error:</p>
  <pre><code>Uncaught TypeError: URL is not a constructor
  </code></pre>
  <p>The string URL does not appear anywhere in the loaded document which leads me to believe that it is not redefined anywhere in my program. I have not been able to find anything other that would explain why this phenomena occurs.</p>
  <p>So my question for a workaround is: Is it possible to access these global constructors in any other way?</p>
