I'm not an active golang user, so it wasn't a comment on that, more just on the GP's assertion that a const had to be an abstracted value. It sounds like that is indeed the case in Go (an implementation choice), but more broadly, I wouldn't expect "const" to mean anything more to most programmers than "give me an error if I or anyone else try to modify this thing."

And in C++, it certainly isn't. Even a constexpr in C++ is a thing you can get a pointer-to— C++'s only guarantee with a constexpr is that it has to be possible to evaluate it at compile time.
