Internally, that's what C++ is doing..Converting the abstractions into code. There is a lot of complexity hidden from view (you might see some of it when you get some esoteric template bug in your ide)

Btw, that code is using std::unordered_map which is notoriously slow compared to an ordinary std::map for a small amount of elements. And the unordered map of register names each with a pair, why? Why not use std::vector for fast lookup?

The crux of what i'm saying isn't anything new, Bjarne Stroustrup admits that C++ is mainly a high-level abstraction language. There is some new things, but really, the things that are new like << etc. are operator overloads which are just more abstractions.
