title: Django :Cant find the args when not using the non-named groups in urls.py
body: <p>Here is the code in urls.py:</p>
  
  <pre><code>urlpatterns = patterns('',
      ('^meta/\d{4}/$',metadata),
  )
  </code></pre>
  
  <p>And in the view.py, i just simply print the request or args:</p>
  
  <pre><code>def metadata(request,*args, **kwargs):
      return HttpResponse(str(args))
      #return HttpResponse(str(request))
  </code></pre>
  
  <p>the problem is that no matter I use the request or the args, I cant not get the <strong>'year'</strong> arg. 
  For example, when i type url:<code>http://127.0.0.1:8000/meta/1990/</code> , it should return <strong>1990</strong>, However it does not.
  According to the Django book, using non-named groups will return args correctly.
  Btw, if i use named-groups, it works fine, args are saved in the kwargs.</p>
