+// An anonymous struct value LITERAL (not to be confused with a
+// struct TYPE) uses '.{}' syntax:
+//
+//     .{
+//          .center_x = 15,
+//          .center_y = 12,
+//          .radius = 6,
+//     }
+//
+// These literals are always evaluated entirely at compile-time.
+// The example above could be coerced into the i32 variant of the
+// "circle struct" from the last exercise.
+//
+// Or you can let them remain entirely anonymous as in this
+// example:
+//
+//     fn bar(foo: anytype) void {
+//         print("a:{} b:{}\n", .{foo.a, foo.b});

+//
+//     bar(.{
+//         .a = true,
+//         .b = false,
