I am thinking about writing actors library, do you think it is required?

Although the issue may not make it very clear, if you look at the documentation for

actor

https://kotlin.github.io/kotlinx.coroutines/kotlinx-coroutines-core/kotlinx.coroutines.channels/actor.html at the bottom there is a note, saying they'll replace the function with something more complex. So they are indeed working on it.

See this branch https://github.com/Kotlin/kotlinx.coroutines/blob/actors-prototype/core/kotlinx-coroutines-core/src/test/kotlin/kotlinx/coroutines/experimental/actors/CrawlerExample.kt

@dave08 I think that branch is obsoleted by this one: https://github.com/Kotlin/kotlinx.coroutines/commits/typed-actors

ok
