Sorry but that doesn't explain anything. Why is just "x" not allowed? What does ".{x}" actually mean?

  .{ x } or .{ x, y, z } etc... are adhoc-constructed anonymous struct-values which can be inspected at compile time by the standard library's string formatting code. It all makes a lot more sense after understanding Zig's comptime features: https://ziglang.org/documentation/master/#comptime https://ziglang.org/documentation/master/#comptime The end of the comptime section also explains how string formatting works that way.
