title: Will OrderedDict become redundant in Python 3.7?
body: <p>From the <a href="https://docs.python.org/3.7/whatsnew/3.7.html" rel="noreferrer">Python 3.7 changelog</a>:</p>
  
  <blockquote>
    <p>the insertion-order preservation nature of <a href="https://docs.python.org/3.7/library/stdtypes.html#typesmapping" rel="noreferrer">dict</a> objects <a href="https://mail.python.org/pipermail/python-dev/2017-December/151283.html" rel="noreferrer">has been declared</a> to be an official part of the Python language spec.</p>

  <p>Would this mean that <a href="https://docs.python.org/3.7/library/collections.html#collections.OrderedDict" rel="noreferrer"><code>OrderedDict</code></a> will become redundant? The only use I can think of it will be to maintain backwards compatibility with older versions of Python which don't preserve insertion-order for normal dictionaries.</p>
