title: Use More than One Sequelize.fn?
body: <p>I see many examples such as:</p>
  
  <pre><code>Model.findAll({
    attributes: [[sequelize.fn('COUNT', sequelize.col('hats')), 'no_hats']]
  });
  </code></pre>
  
  <p>But say you need to use another function in addition to 'COUNT' e.g. <code>sequelize.fn('LOWERCASE'...</code> or <code>sequelize.fn('UNIQUE'...</code>. Is there a way to use more than one <code>sequelize.fn</code> at a time?</p>
  
  <p><strong>UPDATE</strong></p>
  
  <p>I'm looking for a syntax that would let me use two functions in one <code>findAll()</code>... possibly something along the lines of:</p>
  
  <pre><code>Model.findAll({
    attributes: [[sequelize.fn(['LOWERCASE','UNIQUE'], sequelize.col('hats'))]
  });
  </code></pre>
