No language can fix mistakes, but in Rust if you have a() calling b() which calls c(), there is no way* that c can jump to a without any indication of it in b.

No language can fix mistakes, but in Rust if you have a() calling b() which calls c(), there is no way* that c can jump to a without any indication of it in b. You at least need to have `?` somewhere in b. I consider it a really good thing, among other advantages. * panic + catch_unwind, but that's special and not meant or used in practice for error handling
