Problems with Go channels (2016)

Strange to go all this length without mentioning the approaches that solve the problem in that first example:

1. send a close message on the channel that stops the goroutine

2. use a Context instance - `ctx.Done()` returns a channel you can select on

Both are quite easy to grasp and implement.

Hi! No, I think you've misunderstood the assignment. The example posits that you have a "game" running, which should end when the last player leaves. While only using channels as a synchronization primitive (a la CSP), at what point do you decide the last player has left, and where and when do you call close on the channel?
