Doesn't protection from reassignment not exist in most languages anyways? In C++ you should be able to cast away the const. Realistically you probably can achieve this in any language with reflection.

Unless a const is literally a compile time constant inserted through the program, it's likely able to be changed somehow in most languages.

You can definitely protect from reassignment in those languages (e.g. `final` in Java) but they don't completely prevent you from changing the underlying data. Rust would be one that comes to mind that has true immutability. I guess the Go maintainers just didn't want to go down that road, which I get.

Sorry, I guess I read "protect from reassignment" as "protect the underlying data" then.

I would argue that if you CAN change the underlying data, then the understanding of const by 99% of people is made incorrect. Therefore it's not really a good feature (in my opinion).
