Can we have function pointers in Go?

It works if you’re using the signature. There’s no pointer.

type HelloFunc func(string)

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

func main() {
    var hf HelloFunc

    hf = SayHello

    hf("world")
}

Alternatively you can use the function signature directly, without declaring a new type.
