I'm not sure using multiple defer is common. But In the https://tour.golang.org/flowcontrol/12, I think we can mention that defer would put the functions into an extra stack(LIFO)

func main() {
	defer fmt.Println("world")
         defer fmt.Println("world2")
	fmt.Println("hello")
}

// hello
// world2
// world

IMO, we may add a note in the docs or update the code.

I found that https://tour.golang.org/flowcontrol/13 mentioned it.
