All the Typed API is really well defined and you have 2/3 of the Actor model semantics already available:

• spawn new (re)actors
• passing messages between (re)actors

the missing point IMO is

• a (re)actor could change it's behavior

Talking with @axel22 he said that there are alternatives to have this, but I'd like to have it as a first class API from the library.

WDYT?
