I don't see anything that is broken by arrow functions.  You are attempting
to use arrows for defining methods which is incorrect.  This would be
correct:

    function withCircleUtils() {
        this.{
          area() { return this.radius * this.raduis * Math.PI; },
          diameter() { return this.radius + this.radius; }
        };
    }

Do you see a problem with this construction?
