C++ in Constrained Environments
summary
Argues that practical C++ for constrained systems means concrete techniques not slogans: applies C++ Core Guidelines, moves work to compile time (example: integer-sqrt computed at compile time), uses span and chrono for zero‑overhead safety, shows variant replacing unsafe unions, details resource management via RAII and move semantics (vectors reallocate invalidating pointers, moves often cost ≤ six word copies), reports modules speeding builds by 7–80×, and urges executors, pattern matching, static reflection and better packaging.
