Problems with Go channels (2016)

My rule of thumb is that the goroutine that writes to a channel is responsible for closing it. In this case, a deferred call to close the channel in HandlePlayer is sufficient.

Still, this example has other issues (naked range over a channel?!) potentially contributing to the author’s confusion.

However, this post was also written almost a decade ago, so perhaps it’s a result of being new to the language? If I cared to look, I’d probably be able to find the corresponding HN thread from that year full of arguments about this, hah.
