Besides the Move and Leak traits mentioned in this article, there are several changes I would make to the standard library if backwards compatibility wasn't a concern, including: Changing Iterator to make use of Generic Associated Types. Change std::env::set_var to be unsafe. Because using it in multithreaded program causes undefined behavior for any c code that reads the environment (which includes quite a few libc and posix functions). Change channels to have a better API that is mpmc and closer to crossbeam. And probably others I can't think of at the moment.
