golang函数闭包实现波费纳契数列

直接看代码：

package main

import "fmt"

func fibonacci(s1, s2 int) func() int {
   fmt.Println("start with:", s1, s2)
   left := s1
   right := s2
   return func() int {
      nest := left + right
      left = right
      right = nest
      return nest
   }
}
func main() {
   f := fibonacci(0, 1)
   for i := 0; i < 10; i++ {
      fmt.Println(f())
   }
}
