A good panic/reover/Goexit explaination should cover these following cases.

The program exits normally.

package main

func main() {
	defer func() {
		recover() // recover "bye"

(Update: I wrote a more formal article on this topic.)

At a time, there might be multiple unrecovered panics coexisting in a goroutine. Each one associates with one non-exited function call in the call stack of the goroutine. Each non-exited function call may associate with at most one unrecovered panic.

Similarly, at a time, there might be multiple Goexit signals coexisting in a goroutine. Each one associates

	package main

	import (
	"fmt"
	"math/rand"
	"sync"
	"time"
	)

	func main() {

	Assume "returning phase" has been defined elsewhere in Go specificaiton.

	At run time, a fucntion call may call other functions.
	This forms a call stack at any time in each goroutine.
	We call the top call in the stack as the current call.
	Each non-existed call in the stack may associate with at most one panic.

	At run time, panics may occur when the current call is being executed.
	Panics occur either by calling the builtin panic fucntion or
	performing operations that cause runtime panics.

	#include <functional>
	#include <iostream>

	using namespace std;

	class C
	{
	public:
	int foo;
