Well, one can always write unsafe Rust. Although the more usual pattern here is to ditch pointers and instead have a giant array of objects referring to each other via indices into said array. But this is effectively working around the borrow checker - those indices are semantically unchecked references, and although out-of-bounds checks will prevent memory corruption, it is possible to store index to some object only for that object to be replaced with something else entirely later. |

That's what generational arenas are for, at the cost of having to check for index validity on every access. But that cost is only in comparison to "keep a pointer in a field" with no additional logic, which is bug-prone.
