First heard about consteval. This is cool, but every time C++ adds new and obscure features like this I cannot stop feeling helpless. Rust-like macros are fine, and old languages like Java have linter checks that provides type safety to the format string [1].

Aren't these enough? Apparently no.

There could be a world where people stick with this kind of "pragmatic" solution and stay away from without doing spec-puzzle-solving. C++ is not that world and I've accepted that, but let's make sure the other side holds the majority vote.
