-// It is really quite inconvenient having to manually keep track
-// of the active field in our union, isn't it?
-//
-// Thankfully, Zig also has "tagged unions", which allow us to
-// store an enum value within our union representing which field
-// is active.
-//
-//     const FooTag = enum{ small, medium, large };
-//
-//     const Foo = union(FooTag) {
-//         small: u8,
-//         medium: u32,
-//         large: u64,
-//     };
-//
-// Now we can use a switch directly on the union to act on the
-// active field:
-//
-//     var f = Foo{ .small = 10 };
-//
-//     switch (f) {
-//         .small => |my_small| do_something(my_small),
-//         .medium => |my_medium| do_something(my_medium),
-//         .large => |my_large| do_something(my_large),
-//     }
-//
-// Let's make our Insects use a tagged union (Doctor Zoraptera
-// approves).

-// By the way, did unions remind you of optional values and errors?
-// Optional values are basically "null unions" and errors use "error
-// union types". Now we can add our own unions to the mix to handle
-// whatever situations we might encounter:
-//          union(Tag) { value: u32, toxic_ooze: void }
