Show HN: Compile-time typechecked Akka actors (github.com)

This is rather cool and makes me want to look at Scala again if only for this. Is this what is known as a "killer feature"?

This looks very cool. Does anybody have any experience using Typed Actors? Or with Akka Typed?

Why would you name it this? A feature by this name already exists as part of akka. That's confusing and hard to find via google.
