ES6: prevent that = this;

Some days ago I found a solution for following problem in Javascript:

Solve a really ugly problem

I know many lines of code where you find follwing that-this reference

	aCuteFuction: function (a, e)
	{
	//very ugly but necessary to get access to the function scope of the outer function
	var that=this;
	var test = function(e, a){
	//return closure function value
	return that.property;
	}
	}

Now with ES6 you can solve this problem with the arrow function like this.

	aMoreCuteFunction: function (a, e)
	{
	var test = (a,e) => this.property + ' istn it?';
	}

As you can see, you can directly use this in the arrow-function, which is a kind of a shortcut to "function". Thats really nice.
