Web(To clarify @MSalters' comment, a C++ enum's range is based on its underlying type (if a fixed type), or otherwise on its enumerators. In the latter case, the range is based on the smallest bitfield that can hold all defined enumerators; e.g., for enum E { A = 1, B = 2, C = 4, };, the range is 0..7 (3 bits).
