What did you do?

I made a package mypackage with the following code:

package mypackage

import (
	"fmt"
	"reflect"
)

type Helper struct{}

func (Helper) Method1() {}
func (Helper) method2() { fmt.Println("From method2") }

func (h Helper) Print() {
	h.method2()

	for i := range reflect.TypeOf(h).NumMethod() {
		fmt.Println(reflect.TypeOf(h).Method(i))
	}
}

As you can see, the package is very simple. It only has one defined type (Helper) with 3 methods, 2 exported and one private (non-exported). The Print method is used to print method set of the Helper.

main.go is as follows:

package main

import (
	"ceogolang/mypackage"
	"fmt"
	"reflect"
)

func main() {
	h := mypackage.Helper{}

	for i := range reflect.TypeOf(h).NumMethod() {
		fmt.Println(reflect.TypeOf(h).Method(i))
	}

	h.Print()
}

The main function is also very simple, it just initializes the mypackage.Help struct variable and prints its method set (one directly in the main and one by invoking Print method).

What did you see happen?

The std output of the program is:

{Method1 func(mypackage.Helper) <func(mypackage.Helper) Value> 0}
{Print func(mypackage.Helper) <func(mypackage.Helper) Value> 1}
From method2
{Method1 func(mypackage.Helper) <func(mypackage.Helper) Value> 0}
{Print func(mypackage.Helper) <func(mypackage.Helper) Value> 1}

What did you expect to see?

I expect to see method2 in the second print as well, since (looking "directly" at the mypackage) the helper method set also includes method2 (I invoked it in the Print method).
