I haven’t had major issues with sccs yet. The linter enforces forward references so the cycle pain we do have is with dynamic/deffered imports, and it’s usually solved by splitting a module.

If you look at the pyrefly repo (metas new type checker), there are some deep thoughts about sccs, but I didn’t fully grok them.

Thanks for the Pyrefly pointer — I hadn't tracked Meta's Rust rewrite yet. Will dig into their SCC handling.

Your "splitting a module" framing is exactly right. In the IaC world, a Security Group with inline rules is like a Python module with circular imports — it couples identity with logic. The fix is the same: extract the logic into separate resources (or modules), keep the original as a pure identity/interface.

Interesting that the same pattern shows up in both compiler design and infrastructure tooling.
