title: Can I use ES6's arrow function syntax with generators? (arrow notation)
body: <p>That is, how do I express</p>
  <pre><code>function *(next) {}
  </code></pre>
  <p>with arrow syntax? I've tried all the combinations I could think of, and I can't find any documentation on it.</p>
  <p>(I am currently using Node.js v0.11.14.)</p>
