… in turn based on a paper published 25 years earlier. Hello fellow [Lorite](https://anathem.fandom.com/wiki/Lorite) 👋😜

_(@nzok I am aware that you [disagreed with the concept](https://erlangforums.com/t/per-process-atom-limit/3939/23) (which is merely a narrative figure in an alternative-reality fiction novel, [Anathem](https://en.wikipedia.org/wiki/Anathem) (which I happen to especially like 😸)) when @juhlig [mentioned it in another thread](https://erlangforums.com/t/per-process-atom-limit/3939/20), but I would argue that it really depends on what constitutes novelty and the frame one puts a “new” idea in. Applying a **specific** hand-held device like an iPad to a **specific** health-related use case like measuring pulse, yes, that has very likely never been thought of before. Applying **some** hand-held device like a club to **some** health-related use case like hitting an opponent over the head (admittedly that concerns not your own health, and not in a good way), no, people came up with that idea quite a while ago.)_

Yeah, the formatter usually does a messy job on posts done by e-mail 🫤 I kinda got used to it, but it would be great if this could be somewhat improved (@AstonJ). Particularly, I see no point in turning `[]` into 😅
