title: New es6 syntax for importing commonjs / amd modules i.e. `import foo = require('foo')`
body: <p>Previously I could do: </p>
  
  <pre><code>import foo = require('foo');
  </code></pre>
  
  <p>But now that TypeScript (1.5) supports es6 module syntax, what is the correct way to achieve the same in ES6 module syntax.</p>
