SimpleRecord: unscoped enum tuple accessor trick

SimpleRecord.cc

#include <iostream>
#include <string>
#include <tuple>


// See: EMC++, Item 10
namespace {
  using Person = std::tuple<std::string, std::string, int>;
  enum {                    FirstName,   LastName,    Age };
}


int main() {

  Person p{"Erik", "Eriksson", 25};

  using std::get;
  std::cout << get<FirstName>(p) << ' ' << get<LastName>(p) << std::endl;

  // instead of get<0>(p), get<1>(p)
}


/* I guess this could be abused for:

#define Record(...) std::make_tuple(__VA_ARGS__)
#define Accessors(_, ...) enum {__VA_ARGS__}

auto q = Record("Erik","Eriksson");
Accessors(q, First, Last);
  
std::cout << get<First>(q) << ' ' << get<Last>(q) << std::endl;
