/**** Invocation example ****/
var dog = new Dog();
dog.Act(); // obvious single implementation
var talkingDog = new TalkingDog();
talkingDog[TalkingBrain].Act(); // call the TalkingBrain implementation
// Getting a specific implementation is recursive, as via multi inheritance you can implement a method twice in both parent classes, thus requiring double implementation specification
