Have you actually tried coding Rust without IDE support? I have. I code C and Rust professionally with basically only syntax highlighting. As for how lifetimes help? One of the more annoying parts of coding C is to constantly have to look up who owns a returned pointer. Should it be freed or not? And I do not find into() to be an issue in practice.
