For example, consider the following, based on a testcase from https://github.com/llvm/llvm-project/issues/54226

  u16 zip3(u8 a, u8 b) {
      char z;
      return u16{
          a[0],b[0],
          a[1],b[1],
          a[2],b[2],
          a[3],b[3],
          a[4],b[4],
          a[5],b[5],
          a[6],b[6],
          a[7],z
      };
  }
