// This is a classical example of dependency injection.
// My class Car receives an instance of an engine and use it in the run method, where it calls the turnOn method.
// Note that my Car does not depends on any concrete implementation of engine.
// And I'm not importing any other type! Just using a dependency injected instance of something
// that responds to a turn_on message. I could say my class Car depends on an interface.
// But I did not have to declare it. It is an automatic interface!
