I would like to create a type that is an integer value, but with a restricted range. Attempting to create an instance of this type with a value outside the allowable range s
Well, as you noticed, there is already a form of diagnostic for enumerations.
It's generally crude: ie the checking is "loose", but could provide a crude form of check as well.
enum Range { Min = 0, Max = 31 };
You can generally assign (without complaint) any values between the minimal and maximal values defined.
You can in fact often assign a bit more (I think gcc works with powers of 2).
