You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: empty_interface.go
    path of file: ./repos/the-way-to-go_ZH_CN/eBook/examples/chapter_11
    
    the code of the file until where you have to start completion: package main

import "fmt"

var i = 5
var str = "ABC"

type Person struct {
	name string
	age  int
}

type Any interface{}

func main() {
	var val Any
	val = 5
	fmt.Printf("val has the value: %v\n", val)
	val = str
	fmt.Printf("val has the value: %v\n", val)
	pers1 := new(Person)
	pers1.name = "Rob Pike"
	pers1.age = 55
	val = pers1
	fmt.Printf("val has the value: %v\n", val)
	switch t := val.(type) {
	case int:
		fmt.Printf("Type int %T\n", t)
	case string:
		fmt.Printf("Type strin
    
func main() {
	var val Any
	val = 5
	fmt.Printf("val has the value: %v\n", val)
	val = str
	fmt.Printf("val has the value: %v\n", val)
	pers1 := new(Person)
	pers1.name = "Rob Pike"
	pers1.age = 55
	val = pers1
	fmt.Printf("val has the value: %v\n", val)
	switch t := val.(type) {
	case int:
		fmt.Printf("Type int %T\n", t)
	case string:
		fmt.Printf("Type string %T\n", t)
	case bool:
		fmt.Printf("Type boolean %T\n", t)
	case *Person:
		fmt.Printf("Type pointer to Person %T\n", *t)
	default:
		fmt.Printf("Unexpected type %T", t)
	}
