I believe in D one should be able to write a RangedInt(int lowerBound,
int upperBound) type
More precisely: BoundedInt(long lowerBound, ulong upperBound) so it
can express any range of any number.

This is an example, ported from the Boost date time library:

Do you plan to submit this to Phobos? Then it needs a fair amount of work.
- Need support for unsigned numbers
- Need support for floating-point numbers
- The behavior of the limits is odd - why does IntWrapped!(int, 1, 10)
cover [0, 9] and not [1, 10]?
- Limits are adjusted in a Procrustean manner, they should be enforced
instead (at least for the Bounded type being discussed)
- asNumber should be exposed as alias this.
- add, subtract etc. should be operators
- Many other functions need to be added
