Scala has also a history of three implementations of actor
system, until akka is merged into official support (with Akka's
arthur Jonas Bonér becoming CTO of Typesafe).
In vibe.d's case I think first people don't really know that
there is a good fiber based actor system already in vibe.d, for
that I think it would benefit by separating out to be a
standalone library, then add more functionalities like location
transparency of actors in akka. Otherwise people would only
recognize vibe.d as a networking lib, with no intent to look for
actors there.
