Which "my" program?

If that's so important to you then why not simply add the functionality
you want or need, since you have the source. Or why not simply write your own?
If I understand your requirements right then IMO all of them are already possible.
Only the last one "collections of objects at the same 'rank'" I don't understand well.

I've been busy with other stuff, like this one :-)
