It turns out you can't replace all JavaScript functions with arrow functions because they do completely different things with `this` >_<
{ setX: function(x) { this._x = x; } } // works as expected { setX: (x) => { this._x = x; } } // haha nope, corrupts `window` probably

var a = { setX: (x) => { this._x = x; } }; a.setX(67); console.log(a._x); // undefined console.log(window._x); // 67

Of course if you're using both a setter and a getter it can take you quite a while to work out what's going on here -_-
