-// Remember that little mathematical virtual machine we made using the
-// "unreachable" statement? Well, there were two problems with the
-// way we were using op codes:
-//
-// 1. Having to remember op codes by number is no good.
-// 2. We had to use "unreachable" because Zig had no way of knowing
-// how many valid op codes there were.
-//
-// An "enum" is a Zig construct that lets you give names to numeric
-// values and store them in a set. They look a lot like error sets:
-//
-// const Fruit = enum{ apple, pear, orange };
-//
-// const my_fruit = Fruit.apple;
-//
-// Let's use an enum in place of the numbers we were using in the
-// previous version!
-//
-const std = @import("std");
-
-// Please complete the enum!
-const Ops = enum { ??? };
