I think if inheritance is eventually supported then it would be very
confusing having the ':' stand for both subtyping and inheritance.
enum class WindowOptions : unsigned short { A, B, C };
enum class AdvancedWindowOptions : WindowOptions { D, E };
On the other hand if bitfields are supported as well, is the following
what we want?
enum class WindowOptions : unsigned short : 2 { A, B, C }; // ?
enum class AdvancedWindowOptions : WindowOptions { D, E };
Here we have ':' with 3 different meanings.
The following parses just like a real declaration:
enum class WindowOptions { unsigned short A : 2, B : 2, C : 2 };
