Not sure we support the generics use case for mixins at the moment.
(Certainly you can do it with code style ITDs). For a mixin you'd perhaps
want to ensure it shared a type variable with the target, maybe
public <T> BaseService baseServiceMixin() {
return new BaseServiceImpl<T>();
}
And then the infrastructure would do the necessary wiring, but that is just
with me thinking about it for a few seconds.
