title: VALUES clause in SQLAlchemy
body: <p>Is there a way to build a <code>Query</code> object in SQLAlchemy which will be the equivalent of:</p>
  
  <pre><code>SELECT * FROM (VALUES (1, 2, 3)) AS sq;
  </code></pre>
  
  <p>From what I see in the documentation, the <code>VALUES</code> clause appears only in use with <code>INSERT</code>.</p>
