There is no info in this article how to make method chaining if you don't care about inheritance. Here is a example, that can be useful for beginners:

// new Simon().sleep().talk().work().talk();
class Simon {
    public var energy = 0;

    public function new() {}

    public function sleep():Simon {
        energy = 2;
        return this;
    }

    public function talk():Simon {
        trace('My energy is $energy');
        return this;
    }

    public function work():Simon {
        energy--;
        return this;
    }
}
