Superb : )

I like the way you wrote this one, easy to understand and has a good flow.

One of basic patterns; Strategy pattern, encapsulate what varies (behaviors) and make them interchangeable at runtime, so that we can compose behaviors with a lot more flexibility.

Hi Ricardo, indeed. It's 'merely' a strategy pattern.

I think what makes it interesting is in its usage. The fact that an entity class have more than one 1 strategy pattern, makes it alot more composable and a good 'replacement' technique to inheritance in a lot of cases.

What you just describe seems a lot like Strategy Pattern.
