What is the functional core-imperative shell pattern in C++?

It's splitting pure business logic (core, testable, no side effects) from effectful glue (shell: IO, state, timers). Scales poorly alone.

How do actors scale core-shell patterns?

Actors become shells — each handles subset effects, chats via topics. Localizes mess, decouples modules.

Can I use actors in C++ without Asio?

Yes — libcaer, CAF, or roll yours. funkysnakes shows minimal Asio base.

Imagine your C++ app's side effects exploding into one godawful hub. This actor-driven twist on core-shell keeps things modular, sane. But does it deliver in the wild?
