What does "on top of" or "inside it" mean?
Can you show some code? Or even some pseudocode?

Again, I don't understand what any of this means.

Please don't use "overloaded" words. People come from all sorts of
backgrounds and using these words just causes confusion. Instead please
provide the definitions yourself, and add lots of examples to make sure
there's no misunderstandings.

For instance, what you consider a "heterogeneous list" may not be what
other people consider as such. One may understand that as a
std::vector<std::any>.
