@Mason: Hehe, yeah. I haven’t learned to naturally think about invalidations yet, but I saw now that a late contender in the [invalidation competition](https://discourse.julialang.org/t/a-playful-competition-who-can-define-a-method-that-invalidates-the-most-code/47543/46) was more or less exactly this. Perhaps I can get a consolation prize for being the fool who actually put it in “real” code 🙂

@Sukera: That’s of course true and kinda contributes to the overall shakiness.
