title: SyntaxError when calling an async static function
body: <p>I'm playing a bit with async/await of Node 8.3.0 and I have some issue with static function. </p>
  
  <p><em>MyClass.js</em></p>
  
  <pre><code>class MyClass {
    static async getSmthg() {
      return true;
    }
  }
  module.exports = MyClass
  </code></pre>
  
  <p><em>index.js</em></p>
  
  <pre><code>try {
    const result = await MyClass.getSmthg();
  } catch(e) {}
  </code></pre>
  
  <p>With this code I've got an <code>SyntaxError: Unexpected token</code> on <code>MyClass</code>.
  Why is that? Can't use a static function with <code>await</code> or have I made a mistake?</p>
  
  <p>Thank you</p>
