title: better views of javascript polluted global namespace
body: <p>Is there an easy way to see what variables you (or other libraries) have polluted to the global namespace?</p>
  
  <p>In the (chrome) debugger console, typing <code>this</code>/<code>this.window</code> reveals hundreds of objects, even without other libraries.</p>
  
  <p>Is there a way to have it prune all of the standard browser space objects and return globals (or better, categorized by script file)?</p>
