昨天那个在for循环里append元素的同事，今天还在么？

    package main

    import "fmt"

    func main() {
 s := []    int{1,2,3,4,5}
     for _, v:=    range s {
  s =append(s, v)
  fmt.Printf("len(s)=%v\n",len(s))
 }
}

// The loop we generate:
//   for_temp := range
//   len_temp := len(for_temp)
//   for index_temp = 0; index_temp < len_temp; index_temp++ {
//           value_temp = for_temp[index_temp]
//           index = index_temp
//           value = value_temp
//           original body
//   }

    func main() {
 s := []    int{1,2,3,4,5}
 for_temp := s
 len_temp := len(for_temp)
     for index_temp := 0; index_temp < len_temp; index_temp++ {
  value_temp := for_temp[index_temp]
  _ = index_temp
  value := value_temp
  // 以下是 original body
  s =append(s, value)
  fmt.Printf("len(s)=%v\n",len(s))
 }
}

len(s)=6
len(s)=7
len(s)=8
len(s)=9
len(s)=10
