Count on enum C++ automatic

Question

I\'ve come to a pattern when writing enums in C++. It is like this:

class Player
{
public:
    class State
    {
    public:
        typedef enum
        {

The solution stackoverflow.com/a/60216003/12894563 can be improved. We can save enums expressions in a static vector and iterate, obtain min/max and etc

Usage:

#include 
#include 
#include 
#include 

#define make_enum(Name, Type,  ...)                                              \
    struct Name {                                                                \
        enum : Type {                                                            \
            __VA_ARGS__                                                          \
        };                                                                       \
        static auto count() { return values.size(); }                            \
                                                                                 \
        static inline const std::vector values = [] {                      \
            static Type __VA_ARGS__; return std::vector({__VA_ARGS__});    \
        }();                                                                     \
        static Type min()                                                        \
        {                                                                        \
            static const Type result = *std::min_element(values.begin(), values.end()); \
            return result;                                                       \
        }                                                                        \
        static Type max()                                                        \
        {                                                                        \
            static const Type result = *std::max_element(values.begin(), values.end()); \
            return result;                                                       \
        }                                                                        \
}



make_enum(FakeEnum, int, A = 1, B = 0, C = 2, D);

int main(int argc, char *argv[])
{
    std::cout << FakeEnum::A     << std::endl
              << FakeEnum::min() << std::endl
              << FakeEnum::max() << std::endl
              << FakeEnum::count() << std::endl;
    return 0;
