title: String from Django template, but without returning a HTTPResponse
body: <p>I have a query set whose objects I'd like to use to populate a template. One view I have ends with</p>
  
  <pre><code>return render_to_response('entry.json', {'entry_list':r}, mimetype="application/json; charset=utf-8")
  </code></pre>
  
  <p>However I'd like to be able to serialise to json with a template like this without having to return a HTTPResponse. In pseudocode, this might be:</p>
  
  <pre><code>render('entry.json', {'entry_list':r}) #returns a string with the template entry.json
  </code></pre>
  
  <p>Is this possible? If so, how?</p>
