for example:

enum A { a = -10, b = -11, c = -12, d = -13, e = -34}

enum int countOfA = coutOfFields(A); // 5 fields

https://dlang.org/spec/traits.html#allMembers

enum A { a = -10, b = -11, c = -12, d = -13, e = -34}

enum int countOfA = __traits(allMembers, A).length; // 5 fields

static assert(countOfA == 5);
