Ever need a profiler but don't want the hassle of a heavy framework?
I wrote about a simple, hierarchical #ImGui profiler I created for my projects. It's thread-local, has minimal overhead, and only ~500 lines of C++.

POV: You combine C++23's "deducing this" and C++17's CTAD to implement a vector iterator that propagates constness with no repetition (DRY).
Can you spot the mistake? Every LLM seems to be fine with the code!
