.cbCobrust keeps Python ergonomics (indentation blocks, comprehensions, structural pattern matching, f-strings) while adopting Rust's ownership model,
Result<T,E>/Option<T>error handling, and zero-GIL concurrency. The compiler includes an AI-native translation subsystem that closed-loop converts Python libraries into Cobrust under differential testing verification.Design constraints that distinguish it from other Python successors:
