        // instance, it might inject a package-private object from its own
        // package.
        // 
        // So here's the strategy: we generate a separate injector method that,
        // given the assisted parameters, creates the return value and performs
        // member injection on it, named "assistedCreate_FACTORY_RETURNTYPE".
