I’ve been playing with helix for the last few days and I’m wondering if I’m missing something when it comes to performance and prop passing. I’m seeing re-renders happening on a list even when using memoization. If I’m passing clojure maps and functions (wrapped in use-callback hook) via props, should I expect a render only if changed? For comparison, this same setup does optimize rendering if I run reagent. Also, I’ve noticed that if I have a recursive call to a defnc that uses wrap memo, inspecting react tools component tab only tags the first call to the defnc. If I fully qualify the call to the defnc it then adds the memo tag to the profiler. Some quick vids to help explain: https://www.loom.com/share/5813c34f828a45bd844dd492f51655a9 Issue with recursive call: https://www.loom.com/share/dbd6c7cf23e743af9fba837353eba3a9 Link to the repo: https://github.com/brancusi/test-helix

@aramz the videos + github repo is really great for understanding your question

I think there's at least one thing happening I'm sure of

the thing I'm not sure, is the lack of the "Memo" label in the dev tools. I'm worried that could be a bug

but I'm going to set that aside for now, because I think there's another issue that can be fixed in your code
