I believe in D one should be able to write a RangedInt(int lowerBound,
int upperBound) type that would make sure it contains value in the
range specified (that would require runtime checks, but I think that's
acceptable, those check can be disabled in release). Could be suitable
for DayOfWeek, Month, etc.
What about posting that as a [challenge] on the main D newsgroup?
Good idea.
It's also interesting for floating point values between 0 and 1, for
probabilities or whatever field that's normalized.
Heck, even for defining letters, digits, etc.
alias Ranged!(char, 'a','z') letters;
alias Ranged!(char, 'A', 'Z') Letters;
alias Ranged!(char, '0', '9') digits;
Great. I still suggest using "Bounded" instead of "Ranged" to avoid
confusion with anything range. In particular, ranges are open to the
right but bounded are closed.
