@kraythe It sounds like you're precisely describing Agents <http://doc.akka.io/docs/akka/snapshot/scala/agents.html>: actors with a single mutable variable, whom you send functions to to execute on, which will all get executed serially.
I don't know why they're not popular in Akka, but they're there. I know the Clojure people use them all over the place http://clojure.org/agents?responseToken=03d29a81a9ea9b76cff24e1bb1c6dc369 On Sat, Aug 22, 2015 at 6:59 PM, kraythe <kray...@gmail.com> wrote: > Bad example since all strings are immutable.
