Back to the Basics! Essentials of Modern C++ Style
summary
Revisits concrete rules: default to auto by default for locals, prefer range-for with auto& for whole-collection loops, and use make_unique/make_shared instead of new/delete; prefer non-owning raw pointers/references for parameters and return values. Gives numbers: about 3 million C++ users, ~30 libstdc++ contributors, ~5–7 libc++ contributors, and a reported 4x RocksDB speedup after changing shared_ptr calls. Exposes the shared_ptr reentrancy pitfall and prescribes pin a local shared_ptr copy as the cure.
