I don't understand why this never type was introduced at all. Instead functions not returning, shouldn't Rust enforce returning from function and instead use a None in place of never type? Otherwise how will the "Unwinding" of program flow implemented?

How do you enforce returning from exit or a function with a loop that never terminates?

If it never terminates, then it means it runs forever.

Right, so you can't "enforce" a return from the function.
