go - Is there a way to reuse an argument in fmt.Printf?

Question

I have a situation where I want to use my printf argument twice.

fmt.Printf("%d %d", i, i)

Is there a way to tell fmt.Printf to just reuse the same i?

fmt.Printf("%d %d", i)

You can use the [n] notation to specify explicit argument indexes like so:

fmt.Printf("%[1]d %[1]d
", i)

Here is a full example you can experiment with: http://play.golang.org/p/Sfaai-XgzN
