This is exploring a pattern for a stateful class. An alternative idea would be to actually dispatch on a "state" object every time (making the dispatching a real multiple dispatching, I guess). This is conceptually: * When a given method is called dispatch once to find the implementation. * After this, on any method/property use, forward to the implementation. (This includes the initial method call itself.) The once dipatching is a normal dispatching function, just a different decorator because the default is to do nothing (and not to call the function).
