Use golang to implement linked list in functional style

list.go

package main

type Node struct {
	Val  int
	Next interface{}
}

func create() interface{} {
	return nil
}

func insert(list interface{}, n int) Node {
	return Node{
		Val:  n,
		Next: list,
	}
}

func loop(list interface{}) {
	if list == nil {
		return
	}
	var node = list.(Node)
	println(node.Val)
	loop((node.Next))
}
func main() {
	var list = create()
	for i := 0; i < 10; i++ {
		list = insert(list, i+2)
	}
	loop(list)
}
