Official Iterator support after Go 1.23

[leonardodalinky]

It seems that Golang has made a "range-over-function" feature after Go 1.23, which is included in the standard library iter (doc). I wonder if there are plans to implement these newly added interface in the later versions?

For example, we can add a .iter() method to each container types. I believe this would not break the existing logic:

package main

import (
  "fmt"
  "github.com/liyue201/gostl/ds/list/simplelist"
)

func main() {
  l := simplelist.New[int]()
  l.PushBack(1)
  l.PushFront(2)
  l.PushFront(3)
  l.PushBack(4)
  for ele := range l.iter() {
    // Do something
  }
  fmt.Printf("\n===============\n")
}
