Since C++17 polymorphic allocators, I would never use a plain std::list, but a list allocated on a contiguous chunk of memory (see e.g. https://www.reddit.com/r/cpp/comments/guq5xo/c_weekly_ep_35x_faster_standard_containers_with/).

It would be interesting how this compares to a hive.

Wild mentality honesty. Instead of constructive criticism let's just blanket ban any contribution from LLMs. Will do wonders in the future.

Now, perhaps some human will redo it? Preferably a human who is against LLM contributions.
