That's why I would argue for a "safe" keyword. In this sense, the compiler can actually help me write safe code and encourage library authors to do the same. Either safety really matters and performance can be given up for it, or vice versa. I do not believe that Rust is a "reasonably-safe" alternative to C, because C is already reasonably safe if written with safety in mind, but with the added bonus of being simpler. Rust is reasonably unsafe when written with performance in mind, whereas C++ is just unreasonably unsafe.
