Can we have function pointers in Go?

Question

I was learning about pointers in Go. And managed to write something like:

func hello(){

       fmt.Println(\"Hello World\")
}

func main(){

       pfunc := hel

You could do it like this:

package main

import "fmt"

func hello(){

       fmt.Println("Hello World")
}

func main(){
       var pfunc func()
       pfunc = hello     //pfunc is a pointer to the function "hello"
       pfunc()            
}

If your function has arguments and e.g. a return value, it would look like:

func hello(name string) int{

       fmt.Println("Hello %s", name)
       return 0
}

and the variable would look like:

  var pfunc func(string)int
