-// Sometimes you know that a variable might hold a value or
-// it might not. Zig has a neat way of expressing this idea
-// called Optionals. An optional type just has a '?' like this:
-//
-//     var foo: ?u32 = 10;
-//
-// Now foo can store a u32 integer OR null (a value storing
-// the cosmic horror of a value NOT EXISTING!)
-//
-//     foo = null;
-//
-//     if (foo == null) beginScreaming();
-//
-// Before we can use the optional value as the non-null type
-// (a u32 integer in this case), we need to guarantee that it
-// isn't null. One way to do this is to THREATEN IT with the
-// "orelse" statement.
-//
-//     var bar = foo orelse 2;
-//
-// Here, bar will either equal the u32 integer value stored in
-// foo, or it will equal 2 if foo was null.
-//

-pub fn main() void {
-    const result = deepThought();
-
-    // Please threaten the result so that answer is either the
-    // integer value from deepThought() OR the number 42:
-    var answer: u8 = result;
-
-    std.debug.print("The Ultimate Answer: {}.\n", .{answer});

-fn deepThought() ?u8 {
-    // It seems Deep Thought's output has declined in quality.
-    // But we'll leave this as-is. Sorry Deep Thought.
-    return null;
-}
-// Blast from the past:
-//
-// Optionals are a lot like error union types which can either
-// hold a value or an error. Likewise, the orelse statement is
-// like the catch statement used to "unwrap" a value or supply
-// a default value:
-//
-//    var maybe_bad: Error!u32 = Error.Evil;
-//    var number: u32 = maybe_bad catch 0;
