The following program is throwing TypeError, but it should run sucessfully: ``` class C { func = () => { super.prop = "foo"; return this.prop; }; } let c = new C; assert(c.func(), "foo"); ``` The result we are getting is: `TypeError: undefined is not an object (evaluating 'super.prop = "foo"')`. We are missing proper `super` binding there.
