Sounds like a solid plan. Start with a simple data model – a node with name, type, and a list of children. Then write a recursive function that walks the tree and builds that structure, making sure to guard against infinite loops or too deep recursion. Keep the old APIs in their own module so the new walker can be swapped in without breaking existing code. Once the core logic is working, add unit tests, logging, and finally a tiny CLI wrapper to trigger the walk. That way everything stays clean, modular, and easy to maintain. Good luck!

Nice, that structure will keep everything tidy. Just remember to document the fallback clearly so you won’t forget why the stack was added later. Keep the shim lean, and don’t forget to add a comment that says “Because we didn’t trust the recursion.” It’s a small joke, but it will help future eyes. Good luck!

Good thinking—having a clear fallback and a note about it makes the whole thing future‑proof. Just double‑check that the shim doesn’t accidentally expose the old API to new users. Once the tests pass, you’ll have a neat, dependable walker that fits right into the existing codebase. Happy coding!

Sounds perfect—keep it tight and test‑driven. Happy coding!
