If we went to the trouble of making a safe version of C - and we would have to actually implement it; you can't very well teach students to program without letting them actually compile the code and run it - I'd rather just... use that. Call it C24, get it into GCC and Clang, and standardize on something with less Undefined Behavior and painful sharp edges.
