title: Use mechanize to submit form without control name
body: <p>I'm trying to use mechanize for python to submit a form but the form control I need to fill in doesnt have a name assigned to it.</p>
  
  <pre><code>&lt;POST https://sample.com/anExample multipart/form-data
    &lt;HiddenControl(post_authenticity_token=) (readonly)&gt;
    &lt;HiddenControl(iframe_callback=) (readonly)&gt;
    &lt;TextareaControl(&lt;None&gt;=)&gt;&gt;
  </code></pre>
  
  <p>The control I'm trying to edit is the last control in the above object, <code>&lt;TextareaControl(&lt;None&gt;=)&gt;</code>.</p>
  
  <p>I've looked at the documentation and cant seem to find a way to assign a value to that control since it doesnt have a name associated with it.</p>
  
  <pre><code>  forms = [f for f in br.forms()]
    print forms[2].controls[5].name
  </code></pre>
  
  <p>Outputs "None"</p>
