Beyond New and Delete: Engineering Approach with gsl::owner, std::span and clang-tidy

In my previous articles, Beyond new and delete: A Practical Guide to Refactoring Raw Pointers to Smart Pointers and Beyond new and delete: to Weak Pointer , I explained how to refactor raw pointers into unique_ptr , shared_ptr , weak_ptr , and references. But swapping pointer types is only half the battle. A successful refactoring also requires a systematic engineering process — one that combines ownership analysis, modern C++ types, static analysis, and incremental testing to ensure safety and
