 yfiles.module("Life", function (exports) {
        var Person = Class('Person',
            {
                constructor: function (name) {
                    this.name = name;
                },

                toString: function () {
                    return this.name;
                }
            });



        exports.Person = Person;

    });

    yfiles.module("Life.Special", function (exports) {
        function say() {
            console.log("Adding modules at a deeper level works too.");
            return true;
        }
        var Genius = Class("Genius", {
            $extends: Life.Person,
            constructor: function () {
                Life.Person.call(this);
                this._name = "Not set";
            },
            get name() {
                return this._name;
            },
            set name(value) {
                this._name = value;
            }
        });
        exports.say = say;
        exports.Genius = Genius;
    });
    
    /*
    Life.Special.say(); // returns true

    */

The yFiles documentation does not explicitly say you can nest modules but it all works well.
