Request for update(if possible)

After so many years, seems go compiler optimization have changed a lot. One problem is in chapter 2, iface.go, chapter 2. To make the assembly code call the function through itab func pointer,

func main() {
    m := Mather(Adder{id: 6754})
    // This call just makes sure that the interface is actually used.
    // Without this call, the linker would see that the interface defined above
    // is in fact never used, and thus would optimize it out of the final
    // executable.
    m.Add(10, 32)
}

should be changed to

func main() {
	var m Mather
	m = Adder{id: 6754}
	// This call just makes sure that the interface is actually used.
	// Without this call, the linker would see that the interface defined above
	// is in fact never used, and thus would optimize it out of the final
	// executable.
	m.Add(10, 32)
}

Or the assembly code would CALL "".Adder.Add(SB) directly.
