title: Insert into OrderedDict behind key "foo" (inplace)
body: <p>I want to insert a key behind a given key in a <code>OrdedDict</code>.</p>
  
  <p>Example:</p>
  
  <pre><code>my_orderded_dict=OrderedDict([('one', 1), ('three', 3)])
  </code></pre>
  
  <p>I want <code>'two' --&gt; 2</code> to get into the right place. </p>
  
  <p>In my case I need to update the <code>OrdedDict</code> in-place.</p>
  
  <p><strong>Background</strong></p>
  
  <p>SortedDict of Django (which has an <code>insert()</code>) gets removed: <a href="https://code.djangoproject.com/wiki/SortedDict" rel="noreferrer">https://code.djangoproject.com/wiki/SortedDict</a></p>
