>> I also havent found a truly useful realworld use of THIS_ACCESS.

Here's some. Look at the gereric THIS_ACCESS; it returns an object reference, usually THIS. The returned object reference can be any object.

This means that THIS_Access can be used as a broker that decides which object handles the message. This has huge applications. Basically it makes many generic design patterns like Proxy, Broker, Facade, Decorator, Chain Of Responsibility, and most of the creational patterns like Builder, Abstract Factory, and Prototype, very easy to create in VFP
