title: why es6 expport and import is messy
body: <p>I am using babel es6 class:</p>
  
  <pre><code>export class Util{
    async stringy(str){
      return await str
    }
  }
  </code></pre>
  
  <p>then I import it</p>
  
  <pre><code>import Util from '../lib/util'
  </code></pre>
  
  <p>but it is undefined.</p>
