Using async/await in node 7.4 : <p>I thought async/await was supported in node 7.4, however this example does not work:</p>

<pre><code>const Promise = require('bluebird');

async function main(){
  await Promise.delay(1000)
}

main();
</code></pre>

<p>Results in:</p>

<pre><code>async function main(){
      ^^^^^^^^
SyntaxError: Unexpected token function
</code></pre>

<p>How can I use async/await with node 7.4?</p>
