So, you have to use some kind of "variant"? I think this solution still
limits which types can be used. Am I wrong?

No. Field type is also defineable

Bohdan,
If I understand correctly you have some way to split an object into fields.
After you do it, what are your fields, strings? If so, this is good enough

But first glance reveals difference between two:
RTL : all classes are templates and one can adapt

1. unreadeable
2. difficult to handle automatically (by other programs).
