-// We've seen that passing arrays around can be awkward. Perhaps you
-// remember a particularly horrendous function definition from quiz3?
-// This function can only take arrays that are exactly 4 items long!
-//
-// fn printPowersOfTwo(numbers: [4]u16) void { ... }
-//
-// That's the trouble with arrays - their size is part of the data
-// type and must be hard-coded into every usage of that type. This
-// digits array is a [10]u8 forever and ever:
-//
-// var digits = [10]u8{ 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 };
-//
-// Thankfully, Zig has slices, which let you dynamically point to a
-// start item and provide a length. Here are slices of our digit
-// array:
-//
-// const foo = digits[0..1]; // 0
-// const bar = digits[3..9]; // 3 4 5 6 7 8
-// const all = digits[0..]; // 0 1 2 3 4 5 6 7 8 9
-//
-// As you can see, a slice [x..y] defines a first item by index x and
-// a length y (where y-1 is the index of the last item). Leaving y off
-// gives you the rest of the items.
-//
-// Notice that the type of a slice on an array of u8 items is []u8.
-//
