Can panic-recover handling add to the function Group.Go()?

[guodongq]

When the program is processed in multiple goroutines, panic may occur, which will cause main goroutine to crash directly. Can following logic add to Group.Go() ?

// Go calls the given function in a new goroutine.
//
// If the function returns an error it is added to the group multierror which
// is returned by Wait.
func (g *Group) Go(f func() error) {
	g.wg.Add(1)

	go func() {
		defer g.wg.Done()

+		defer func() {
+			if r := recover(); r != nil {
+				g.mutex.Lock()
+				g.err = Append(g.err, fmt.Errorf("%v", r))
+				g.mutex.Unlock()
+			}
+		}()

		if err := f(); err != nil {
			g.mutex.Lock()
			g.err = Append(g.err, err)
			g.mutex.Unlock()
		}
	}()
}
