title: Export array as an es6 module
body: <p>For some reason I'm unable to use an array exported as an es6 module:</p>
  
  <pre><code>export const choices = [
    ['first', 'First'],
    ['second', 'Second'],
    ['third', 'Third'],
  ]
  </code></pre>
  
  <p>Then:</p>
  
  <pre><code>import { choices } from './constants'
  console.log(choices) // undefined
  </code></pre>
  
  <p>If I simply declare the <code>const</code> in the same file where I'm trying to use it, it works as expected.</p>
