I think that this is a good idea. There is part of me that wants it
the old way. But, I think it's one of those things were the old way
may have promoted bad practice.

So the new way encourages `("%d"):format(3.0)` (or some home-brew
shortened version of the same), which is more verbose but is also
explicit and that's a good thing.
