Moreover, at some point the rubber meets the road and some "unsafe" code almost certainly must exist at that point. The goal should not be to have zero lines of unsafe code, but to have so few that it is possible to review and understand them and to understand why, though they are "unsafe", they yield safe behavior. Rust does do this!
