Guideline Support Library (GSL)
summary
Five concrete GSL features and how they behave: gsl::finally runs a lambda on scope exit so cleanup always executes across returns and exceptions; gsl::narrow checks runtime conversions and throws on out‑of‑range (example: int→char fails at 300); gsl::not_null enforces nonnullable pointers as a compile‑time contract and aborts if constructed from null; gsl::owner is a syntactic ownership annotation for static analysis; gsl::span provides bounds‑checked views. Install via vcpkg or clone GitHub and include gsl/gsl.
