iguana支持匿名类么？该如何写

[171930433]

struct AS
{
struct IAS{
double y;
};

REFLECTION(IAS,y);

double x;
IAS x2;
};

REFLECTION(AS,x,x2);

int main() {

  AS a;
  std::string str;
  iguana::to_json(a,str);

  std::cout << str <<"\n";

  return 0;
}

编译失败：
no matching function for call to ‘to_json_impl(std::__cxx11::basic_string&, AS::IAS&)’

Could you try:

struct AS
{
struct IAS{
double y;
};

double x;
IAS x2;
};

REFLECTION(AS::IAS,y);
REFLECTION(AS,x,x2);

int main() {

  AS a;
  std::string str;
  iguana::to_json(a,str);

  std::cout << str <<"\n";

  return 0;
}
