how does this compare to the inbox and supervisor model of erlang/elixir?

yetihehe•25m ago

It doesn't. It's "promise" based, not "communicating sequential processes". Erlang has more preemptive scheduling, a "thread" can be preempted at any time, here you can only be synchronized when you wait for result. It is called "actor-based", because only functions tagged as "actor" can call waiting functions.

This is more node.js-like communication than erlang.

Apple uses it for iMessage I believe.
