Beautiful way to create a singleton in Go

singleton.go

package singleton

var Instance *_Singleton

type _Singleton struct {
  SharedResource int
}

func _Load() {
	Instance = &_Singleton{SharedResource: 1}
}

func init() {
	_Load()
}

package main

import (
  "fmt"
	"singleton"
)

func main() {
	fmt.Println(singleton.Instance.SharedResource)
}
