I don't see the benefit of these forms versus

struct Object {
        int id;
        float mass;
}

respectively

enum Process {
        CONSTRUCT,
        RUN,
        DESTROY
}

or did you miss that these are available?

That's not possible indeed. It might be handy, please open a bug ticket.

Thanks,
