The main way to make the compiler more forgiving is to use Rc<RefCell<T>> (and Arc<Mutex<T>> when you need thread-safety) to move borrow checking from compile time to run time. Please avoid doing that, though --- it's ugly, it can be slow, and the borrow checker is usually yelling at you for a good reason. There are also some immature crates for tracing garbage collection in Rust, like rust-gc, which typically has higher throughput than reference counting.
