title: ES6 imports in Node with --experimental-modules
body: <p>Trying to use ES6 imports in node with the -experimental-modules flag.  Specifically:</p>
  
  <pre><code>mkdir ma
  cd ma
  npm init
  npm i --save moving-averages
  touch index.mjs
  </code></pre>
  
  <p>Now place the following code in index.mjs:</p>
  
  <pre><code>import {
  ma, dma, ema, sma, wma
  } from 'moving-averages'
  
  ma([1, 2, 3, 4, 5], 2) 
  </code></pre>
  
  <p>The result is:</p>
  
  <pre><code>file:///home/ole/ma/index.mjs:2
    ma, dma, ema, sma, wma
    ^^
  SyntaxError: The requested module does not provide an export named 'ma'
      at ModuleJob._instantiate (internal/loader/ModuleJob.js:86:19)
      at &lt;anonymous&gt;
  </code></pre>
  
  <p>Thoughts?</p>
