Zen and the Art of Code Lifecycle Maintenance
summary
Six concrete takeaways: define six orthogonal qualities (correctness, applicability, reliability, efficiency, evolvability, reasonability), use the type system and tests as primary tools, and treat IO errors and logic-contract errors differently. Techniques demonstrated include property-based testing (Catch generators) and fuzzing, C++23 std::optional .map/.or_else and mention of std::expected / Boost.Outcome, plus Compiler Explorer comparisons that show an immediately‑invoked lambda version can save ~40 assembly lines versus naive code.
