I just wanted to point to something!
summary
Covers practical C++ pointer and pointer-like choices with concrete tradeoffs and small benchmarks: use references for non-null borrows, std::unique_ptr for sole ownership, and std::string_view for non-owning string slices. Explains when iterators are better than raw pointers for container elements, when to use observer_ptr or optional<T> to represent nullable pointers, why std::shared_ptr adds refcount overhead and can hurt hot paths, when std::byte is the correct raw-buffer type versus legacy void*, and how allocators and move semantics affect whether objects must be copied or can be transferred.
