If you use numStr[] instead of numStr, it works. But I see no reason why to!() can't be made to work with a static array. Ideally, it would either turn it into a const ref or a dynamic slice itself, thus avoiding creating a copy, but right now it just fails. Maybe that's just how things go with static arrays, but it seems overly restrictive in this case. to!() shouldn't _need_ a dynamically allocated array.
