This focus on compiler usability is really fantastic. C calls these "compiler diagnostics" for a reason - they should help the programmer diagnose and fix the problem. I loved it when Clang started making C errors sane (and getting GCC to introduce better messages too!), and I'm glad to see Rust take the next step. Since I'm stuck in C++ for the time being, I'm (selfishly) hoping that Clang takes a page from these new Rust errors - these sorts of diagnostics would look great on C++!
