My proposal with conceptual implementation that you can run but the
implementation does not have the exact implementation as one with
std::variant<T&...> would have, like I could modify it but it would never
be one to one, so see my implementation as a conceptual implementation
roadmap meant to show how bookkeeping helps rather than showing the exact
semantics of my implementation.
I also fixed some Typos and grammar mistakes (in the code example section)
that were in my updated docx file.
