I'm reminded of one positive remark made here: https://loglog.games/blog/leaving-rust-gamedev/#ecs-solves-the-wrong-kind-problem https://loglog.games/blog/leaving-rust-gamedev/#ecs-solves-t... > The key point being, this allows a language like Rust to completely side-step the borrow checker and allow us to do "manual memory management with arenas" without actually touching any hairy pointers, and while remaining 100% safe. If there was one thing to point at that I like about Rust, it'd be this. Especially with a library like thunderdome it really feels that this is a great match, and that this data structure very well fits the language as it was intended.
