package mainimport (    "fmt")func main() {    s := []interface{}{1, 2, 3, 4, 5, 6, 7, 8}HERE:    for k, v := range s {        if v == 4 || v == 6 || v == 7 {            // temp := s[k+1:] -> error            fmt.Println("k", k)            temp := make([]interface{}, 0)            for _, v := range s[k+1:] {                temp = append(temp, v)            }            fmt.Println("temp1", temp)            s = append(s[:k], "(")            fmt.Println(s)            s = append(s, []interface{}{fmt.Sprintf("%d", v), fmt.Sprintf("%d", v)}...)            fmt.Println(s)            s = append(s, ")")            fmt.Println(s)            fmt.Println("temp2", temp)            s = append(s, temp...)            fmt.Println(s)            goto HERE        }    }}
