Golang decorator

package main

import (
	"fmt"
)

func decorator(f func(s string)) func(s string) {

	return func(s string) {
		fmt.Println("Started")
		f(s)
		fmt.Println("Done")
	}
}

func doSomething(s string) {
	fmt.Println(s)
}

func main() {

	decorator(doSomething)("Do something")

}

What about method example?
