Not sure either, but empty called on a string should be evaluatable at compile time. You should file a bug with a minimal example.

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.
