Using a `sync.WaitGroup` in place of the `done` channel would be correct, but perhaps less useful: it's about the same amount of code, but you can `select` on the channel but not on the WaitGroup. (That said, a WaitGroup *would* avoid a pointer indirection: channels are reference types, whereas WaitGroups are value types. That difference is the motivation behind my proposal in https://golang.org/issue/28366.) -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
