I've using Js for quite some time, and the behavior of prototype chain and instanceof always give me headache when I'm trying to do simple inheritance...

For now, I'll keep using `_.create` to do Inheritance. Of course it means another library to keep using and more verbose. But whatever...

    var Person = function(){ User.call(this) };

    Person.prototype = _.create(User.prototype, { 'constructor': Person });

    var p = new Person();

    p instanceof User //true
    p instanceof Person //true
