Congratulations and thanks for the public release!

Wish Z a fast growth and wide adoption.

At a glance I'm especially curious how 

> M GHC lightweight threads scale on N event loops

is achieved, does it touch the internals of GHC RTS scheduler? Seems libuv would have to be deeply integrated, how is that done?

> The project's goal is not to compete with the base, but to provide an alternative engineering toolkit, which is more suitable for writing practical network/storage services. Similar to [netty](https://netty.io/ <https://netty.io/>) for java or [nodejs](https://nodejs.org/ <https://nodejs.org/>) for javascript. Welcome to join Z.Haskell if you have a similar use case. Currently, we're heading with the following roadmap:
> + Crypto library based on [botan](https://github.com/ZHaskell/z-botan <https://github.com/ZHaskell/z-botan>).
> + TLS network stack.
> + HTTP framework.
> + Distributed system algorithms.
> Happy hacking!
