> "in C++26 vector::operator[] will be checked" Every major project in that cares about perf and binary size would disable the option that compiler vendors would obviously provide, like -fno-exceptions. Rust memory and type system offer stronger guarantees, leading to better optimization of bound checks, AFAIK. There are more glaring issues to fix, like std::regex performance and so on.
