[BUG] arrow functions with Ember.computed have this as undefined

Declaring a computed property as

fullName: Ember.computed('firstName', 'lastName', ()=>{
    return this.get('firstName') + ' ' +this.get('lastName');
})

it is transpiled into,

define('hello-world/components/a-name', ['exports', 'ember', 'hello-world/templates/components/a-name'], function (exports, Ember, layout) {

    'use strict';

    var _this = undefined;

    exports['default'] = Ember['default'].Component.extend({
        firstName: "sivakumar",

        lastName: "kailasam",

        fullName: Ember['default'].computed("firstName", "lastName", function () {
                      return this.get("firstName") + ' ' +this.get("");
        })

    });

});

_this = undefined seems to be wrong to me, is this a genuine issue or am I using arrow functions in a wrong way?

@bartocc Yes, you must use the old-style anonymous function, not the arrow functions. Arrow functions, by definition, are bound to their lexical scope and the scope cannot be changed. If you need to access this in your property, an arrow function simply won’t work.
