// How to define a type safe enum list using the ENUM_CLASS macros?
// ===============================================================
// To get an enum list like this:
//
//     enum class MyEnums {
//         Value1,
//         Value2,
//         ...
//         ValueN
//     };
//
// ... write this:
//
//     ENUM_CLASS(MyEnums) {
//         Value1,
//         Value2,
//         ...
//         ValueN
//     } ENUM_CLASS_END(MyEnums);
//
// The ENUM_CLASS macros will use C++11's enum class if the compiler supports it.
// Otherwise, it will use the EnumClass template below.


#define ENUM_CLASS(__enumName) \
    enum class __enumName

#define ENUM_CLASS_END(__enumName)
