I misunderstood what you were trying to do. I thought you were just 
trying to get a valid range, missed the requirement that the range works 
with sformat (obviously from the subject! sorry).

Indeed, there isn't a way to extract an actual char[] from Array (and 
this is intentional).

But as Seb says, you can use formattedWrite:

auto rng = str[];
rng.formattedWrite("%s:%s", "some", "string");
