Empowered? Sure. But it seems no one likes using that power for long stretches of time. Rust gives the same power and it gets used far more usefully IME.

Well, we can take `std::variant`, `std::optional`, and `std::expected` out of that pool because the committee hamstrung them from their better alternatives that already existed in Boost for silly, misguided reasons.

C++ libraries have, historically IME, been far more likely to ask you to juggle live grenades while dancing in a minefield than Rust libraries and APIs have.
