Service injection into service doesn't produce code:

Application Universe {
    basePackage=org.helloworld

    Module milkyway {

        Service MoonService {
            String sayHello(String moonName);
        }

        Service PlanetService {
            > @MoonService
        }
    }
}

produces
        <bean
                class="org.helloworld.milkyway.serviceimpl.PlanetServiceImpl" id="planetService">
        </bean>

and no variable, setter and getter in PlanetServiceImpl
