Hello,
Weren’t method calls originally referred to as messages in SmallTalk?
The problem is not message passing, but the complete absence of type safety
when doing so. It is quite ironic that it is developed in part by a company
called “TypeSafe”.
As it is, you can send any object to any actor, no matter how absurd it may
be. The compiler will never catch sending the wrong object. Thanks to the
robustness of Akka, a completely wrong object may not even cause much noise
during runtime. If you intended to send a case class and forgot the constructor
arguments, it will just send the companion object instead, with typically
puzzling consequences.
I am very happy to hear that typed actors are planned for Akka 3.
Best, Oliver

Subject: Re: [akka-user] Use TypedActor or something else
Hello Vladimir,
The typed actors in 2.x are not the best solution and introduce some overhead
on invoking them.
In general you should accept the fact that the network is message based anyway
and it's more powerful to express things as messages (you reason about messages
then),
instead of hiding them under "what looks like a method".
If you're wondering if we're going to remove the current typed actors from 2.x,
the answer is no - they're still useful (mostly as integration point with
legacy code though).
We're aiming to reimplement typed actors to be proper and included in Akka 3,
but that's a long time ahead of us yet (1+ year).
