Are you?
C++ doesn't check bounds by default, and Rust only checks in certain situations and you could opt out if you wanted to instead of switching to asm
- ErroneousBosh 2mo agoC++ is tremendously bloated though, and wastes hundreds of instructions with stuff you shouldn't need to care about.

- zabzonk 2mo ago> I literally have never found a place where `std::variant` has any positives that can't be written a different, clearer way with drastically better compile time and run time performance. So, don't use std::variant? To produce performant output from a C++ compiler, you have to make the same sort of informed decisions that you would if you were writing assembler. Possibly not using the standard library at all.
