Conditional receive on channel

Something like channel.receiveWhen { predicate }. Might be useful if there are multiple worker coroutines, each one processing its own subset of elements.

@fvasco The key difference here is that an element sent to Channel is never lost. It must be received. However, an element sent to BroadcastChannel will be lost if there are no subscribers. It is especially important when creating back-end pipelines to process event, perform protocol conversion, etc.

It is abandoned for a reason. Thanks for bringing attention to it. It is conceptually really hard to implement. If you need something like it, then launch a separate coroutine to perform filtering, so that it sends the correspondingly filtered items to the appropriate downsteam channels.
