title: ES6 import equivalent of require() without exports
body: <p>By using <code>require(./filename)</code> I can include and execute the code inside <em>filename</em> without any export defined inside <em>filename</em> itself.</p>
  
  <p>What is the equivalent in ES6 using <code>import</code> ?</p>
  
  <p>Thanks</p>
