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

A function is also a type in Go. So you can essentially create a variable of type func signature. So following would work;

var pfunc func(string)

This variable can point to any function that take string as argument and returns nothing. Following piece of code works well.

package main

import "fmt"

func SayHello(to string) {
    fmt.Printf("Hello, %s!\n", to)
}

func main() {
    var pfunc func(string)

    pfunc = SayHello

    pfunc("world")
}
