Erlang and Object Actors

Is there any difference between actor objects and message passing in Erlang? From looking at an example chat server in Erlang, it seems not. Below, I've converted a chat example in Erlang into my theoretical language I call Impulse, which is an object-functional language. My friend Steve Dekorte also has the same opinion about Erlang.
