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()
        }
    }()
}
