这个题目有点怪

package main

import "fmt"

type student struct {
   name string
   age  int
}

func main() {
   m := make(map[string]*student)
   stus := []student{
      {name: "pprof.cn", age: 18},
      {name: "测试", age: 23},
      {name: "博客", age: 28},
   }

   for _, stu := range stus {
      m[stu.name] = &stu
   }
   for k, v := range m {
      fmt.Println(k, "=>", v.name)
   }
}

这段代码为何会显示
