Actually in Rust you have a problem where you can't express partial access to a struct at a function level. This means that you can't put some code into a separate function right now, making use of closures/iterators harder. There are attempts to fix this ([1] [2]). If borrow checking is done on collections of objects instead, the problem can be tackled more easily I think.
