C++ 20 Concepts

I don't think we have to worry about C++ 20 concepts because we have evidence coming from these successor languages. Swift has the protocols, Rust has the traits. I've been going through and like creating new kinds of fundamental data types. So if you have a template with the template parameter list class foo, that's a current,. that's the regular class template. But if you have generic with the template argument list classfoo, that will actually be a class generic. Now Foo is a gen, uh, is a class generic and that will actually allow you to see the members of that class at definition.
