> People say this all the time, but in practice, no, Rust's type system will not be used to prevent logic bugs, any more than model-checked C will be used to prevent random bugs in OpenBSD's C code.

I know that's your hobby horse, and I said "theoretically" specifically to head off this argument. I am also skeptical that type systems will prevent logic bugs like this in practice. I'm skeptical of formal methods for the same reason. (Of course, type systems are just simple formal methods.)

I would call it more of a professional horse.
