Question

What better? enum class StateEnum { X=0, O, NONE,COUNT}; constexpr std::string_view get_string(

StateEnum state,
const std::array<std::string_view, 3>& arr) {
return arr[static_cast<size_t>(state)];
}
or directly?
arr[static_cast<size_t>(state)];

but if take plain enum then i can get by without all of it, how better to do, refuse scoping && type safety to easy accsses to elements?
