The fact that by default array access is bounds checked in Rust and by default it isn't in C++ disproves that. I think you would have a hard time convincing the C++ standards committee to put a checked container in the standard, maybe now with the negative publicity maybe but definitely not before. I'm guessing it would be impossible to get an unchecked container into the rust stdlib.
