Decent primer on ES6 class syntax.  

1. Should use `TypeError` for the error message for an abstract class.

2. Missing class field declarations[0] (stage-3, but eminent).

    class Foo {
      bar = 'instance';
      baz = () => console.log(`I'm context bound to ${} yo!`);

    var f = new Foo();

Aside: Been working with InDesign's ExtendScript the past few weeks, it's been extremely painful.  Won't even shim to ES5 completely/properly, cheating just to get most of ES5, and ES6 modules with Webpack.
