-// Zig has an "unreachable" statement. Use it when you want to tell the
-// compiler that a branch of code should never be executed and that the
-// mere act of reaching it is an error.
-//
-// if (true) {
-// ...
-// } else {
-// unreachable;
-// }
-//
-// Here we've made a little virtual machine that performs mathematical
-// operations on a single numeric value. It looks great but there's one
-// little problem: the switch statement doesn't cover every possible
-// value of a u8 number!
-//
-// WE know there are only three operations but Zig doesn't. Use the
-// unreachable statement to make the switch complete. Or ELSE. :-)
