It's not an exception to const.

You may perhaps have misunderstood the proposal. The type T..U is
sugar for struct { T begin; U end; }, that's all. The value x..y is
just an instance of typeof(x)..typeof(y). There's no array magic going
on whatsover. You'd use ranges to /slice/ arrays, that's all.
