No need Mutex if you use Channel. Am I right?

I'm talk about https://github.com/olahol/melody/blob/master/hub.go#L34-L36 and code below

[ianberdin]

Access tot hub.session already synchronous, because channels not buffered.

It's code totally synchronous...

[olahol]

It's locked because hub.sessions can be accessed asynchronously by hub.len().

What's the problem with https://github.com/olahol/melody/blob/master/examples/gophers/main.go ?
