auto main() -> int {
  auto wd1 = parse<week_day>("wednesday");
  console::write_line(wd1);
  auto wd2 = enum_object<>::parse<week_day>("WEDNESDAY", true);
  console::write_line(wd2);
  auto wd3 = parse<week_day>("2");
  console::write_line(wd3);
  try {
    auto wd4 = parse<week_day>("january");
    console::write_line(wd4);
  } catch (const system_exception& e) {
    console::write_line("Exception : {}", e.message());
  }
