So you miss your good old, jquery.extend?

node-extend.js

Object.defineProperty(Object.prototype, "extend", {
    enumerable: false,
    value: function(from) {

        var props = Object.getOwnPropertyNames(from);
        var dest = this;

        props.forEach(function(name) {
            if (name in dest) {
                sys.puts(sys.inspect(this));
                var destination = Object.getOwnPropertyDescriptor(from, name);
                Object.defineProperty(dest, name, destination);
            }
        });

        return this;
    }
});
