A modern programming language that makes developers happier.

kotlinlang

Don't know if this is the right channel, but does something an async task queue exist where I provide a coroutine scope in which callbacks can be scheduled to be executed sequentially or simultaneously?

this could be done with channels, where the channel contains the callbacks (“tasks”); you could configure buffering (or not) for channels), concurrency (how many coroutines) for task execution, error handling strategies, etc.

That looks very promising, thank you very much

If you have a specific use case you can open an issue or fork

What you described just sounds like core coroutines functionality, not sure why you’d need to use a channel, let alone a library, for this. 

Can you describe what you're trying to do? It's likely there is a simpler solution
