What is the best way to spawn two actors that talks to each other?

[Escapingbug]

I have a situation that needing two actors talking each other.
Originally I was thinking about saving ActorRefs in two actors, which seems to be a problem as no one could be spawned since they both need another one to be spawned first.
My current thought is to use the OutputPort, so that one could use the output port to spin up first then be passed to another one.
The problem is, I'm not sure the OutputPort is exactly designed for this purpose, and this seems to be a little bit low-level as I need to do some pub-sub preparation works for this situation.
Is there better way to achieve this?

Generally it's not super easy to set up two actors with references to each other since that forms a cycle. What normally you would do start actor a, then start actor b passing a handle to a in B's startup routine. You and then send a message to actor a that b is running, and past the handle to b. Then they can send messages to each other.

However if you only need one actor to call the other and get a reply, that's what RPC is for. If you have a toy sample or a gist I could maybe give more guidance
