In for-range aContainer may be not a anonymous copy

[Bububuger]

Hi, I'm studying go101 website, which gives me a lot of inspiration.

In https://go101.org/article/container.html, about for-range section
when aContainer is an arrary, modification about aContainer has effects on it.

package main

import "fmt"

func main() {
	type Person struct {
		name string
		age  int
	}
	persons := [2]Person {{"Alice", 28}, {"Bob", 25}}
	for i, p := range persons {
		fmt.Println(i, p)

		// Now this modification has effects
		// on the iteration.
		persons[1].name = "Jack"

		// This modification has not effects on
		// the persons array, for p is just a
		// copy of a copy of one persons element.
		p.age = 31
	}
	fmt.Println("persons:", &persons)
}

output is :

0 {Alice 28}
1 {Jack 25}
persons: &[{Alice 28} {Jack 25}]

and i tried to print the addresses of the origin persons out of for-range and the 'copyed' persons in for-range , they are the same!

by the way, i'm using the go1.14

I get the following output:

0 {Alice 28}
1 {Bob 25}
persons: &[{Alice 28} {Jack 25}]

What does the go env output on your machine?

ooooh, i am so sorry! i got it wrong.
output is:

0 {Alice 28}
1 {Bob 25}
persons: &[{Alice 28} {Jack 25}]

there is no problem this section.
