In Golang, is it possible to change a pointer parameter's value to something else?
For example,
func main() {
i := 1
test(&i)
}
func test(ptr interface{}) {
v := reflect.ValueOf(ptr)
fmt.Println(v.CanSet()) // false
v.SetInt(2) // panic
}

Is it possible to have test()
change i
to point to another value 2?
