With that change, then you can compile my original suggestion, or my later suggestion.

Actually, it seems that even args.join(" ") works, without changing to the tail-const type...

That is technically correct, but I'm not sure why. I would have expected isInputRange!(const string[]) to be false.

Ah, it is false. But IFTI is removing the head-constness of it (that was the feature I was thinking of).

But it doesn't remove the head-constness of the element type! I don't know if there is a correct way to do this. We probably need to add a new template constraint that examines the most permissive legal copy of a range is.
