Cobrust is a statically typed Python successor implemented in Rust with an AI-native compiler that closed-loop translates the Python ecosystem. It keeps Python ergonomics (indentation blocks, comprehensions, pattern matching, f-strings) while adopting Rust's ownership model and Result/Option error handling. No GIL, no implicit truthiness, no mutable default arguments. Targets Cranelift and LLVM backends. File extension: .cb
