Yes, I wanted to point out Lanes as well, as an honourable exception.

And many argue that share-nothing concurrency is superior.

No reason why shared references to _user data_ could not be allowed,
although of course they need to be protected by a mutex. I like the
Rust approach, where you temporally get a mutable reference and
promise to give it back quickly
