Not really. You just need to make the underlying fields private and provide methods to get slices to the data you need.

I can make it a granny smith, a pink lady, a Gala, a Cosmic Crisp and the shape and color striations change. I can see the tiny little pore circles when it's a green or yellow apple. I can conjure and catch my fingernail on a worm hole in the apple.

If I think about a wild green apple from apple trees I know about in Seattle, I can see myself standing there, seeing them both on the tree, and sitting on the ground rotting in several different states of decay and I can squish them and feel it crunching and squishing underfoot, with some parts just sinking into the soft spring soil at a tree on one side of town, or grinding into the gravel and asphalt on the other side of town. I could pinpoint these trees for you on a map.

I can put myself in the scene from Oppenheimer in the lab at Cambridge where he poisoned the apple in the movie, and I can pick up the apple and see the injection site. If I really try I can detect the faintest smell of almonds as I hold it up to my nose. I can do it as Bohr. I can grab the apple out of Bohr's hand as Oppenheimer and feel his adrenaline and the resistance of his confused hand as I do it. I can throw it against the wall instead, maybe shattering a glass window and hearing and seeing all of that, then cutting myself while cleaning it up and smelling and tasting the blood because I instinctively sucked on it.

Mind's eye is so much more than just visual, that the article and discussion of mental imagery in this thread is a bit flat.

Even the survey assumed that every aspect of someone's mind's eye is entirely visual, and it's just not the case.

In Uk they made studies about this: https://www.kcl.ac.uk/news/up-to-90-of-middle-aged-and-older...

People can differentiate quality from shit.

You definitely can and this is done a lot. What you might mean is that you can't use standard library's collections with them (this is getting stabilized soon!) and have to use third-party, but that is a different thing than "can't use arenas".

> Rust is not a good choice for this kind of tricks.

Rust can do those tricks, but it's true that it is hard than in C or Zig. That said there are often crates to help.

Hmm wait a minute, unless that small minority is politically well connected with a lot of media access. Then they could manufacture a fake backlash. Much like the backlash to "woke!" Ok nevermind it is the same.
