Hi, is there an empty ReceiveChannel available in kotlinx.coroutines ?

No, but you can do `produce {}`. What is your use-case for it?

Yes, I wrote
```
private val EmptyChannel = produce&lt;Nothing&gt; { }

fun &lt;E&gt; emptyChannel(): ReceiveChannel&lt;E&gt; = EmptyChannel
``` I just wondered if there was already something. thanks

Please consider filing an issue to <https://github.com/Kotlin/kotlinx.coroutines/issues> explaining your use-case. PR would be welcome, too. 

Basically we have the following interface:
```
interface MyInterface {
	fun openEventSubscription(): ReceiveChannel&lt;Event&gt;
}
```

Of course most implementations would delegate the subscription to a `BroadcastChannel` or use `produce` to create a channel.

But, in some edges cases and in tests the implementation may simply want to return an empty channel

Do you think it makes sense ? Should I submit an issue or a PR ?
