How do you figure this is a business logic bug? It looks like a pretty clear-cut implementation bug to me. Rust would 100% have caught this bug, and in fact I'm pretty sure it would have caught the bug at least two different ways: 1. The reference outlives the original value. 2. You can't have multiple mutable references at the same time.

> 2. You can't have multiple mutable references at the same time. If I understood the issue correctly, only one of the references would be a mutable one, so the way Rust could have caught the bug would instead be the related rule: "you can't have an immutable reference and a mutable reference at the same time".
