+// 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,
+// });
+//
+// The example above prints "a:true b:false".
