Isn't that the trick used to test for infinite ranges? Infinite ranges are
defined to have an  'enum bool empty = false' member. So, for an infinite
range, 1+Range.empty is a compile-time expression that can be used as
dimension for a static array.
Else, .empty is a function and I suppose the is() returns false.

Or something like that, anyway.
