The thing is, there are several groups - it's not as if all additions
were guaranteed to be at the end. So either we play with renumbering
again and again, or we are back to the square one...

Is there any common trick that would allow to verify the lack of duplicates
at the build time?

Or we can reorder the list by constant value, with no grouping visible
anywhere...
