title: ES6 and window / global variables
body: <p>I'm working with es6 modules. In some of them I use lodash. My question is - is it possible to load lodash as global variable, or it should be imported in all files separately? I tried this in my initializer:</p>
  
  <pre><code>import lodash from 'lodash';
  window._ = lodash;
  </code></pre>
  
  <p>Also this way:</p>
  
  <pre><code>window._ = require('lodash');
  </code></pre>
  
  <p>But it doesn't work. In my modules I get errors when use, for example,  _.truncate:</p>
  
  <blockquote>
    <p>TypeError: Cannot read property 'truncate' of undefined</p>
  </blockquote>
