I mean if you do an off by one error on indices, essentially you are readin the pointer of another node.
This is a common argument about Rust. Unlike pointer confusion, with index confusion, you still get bounds checking in the containing collection, and you also avoid type confusion (the wrong index element will still have the same type as the object you intended to access). So there are still some benefits.
