Explanation: This makes the access to
std::optional's wrapped value null-safe in Swift. It also allows using if-let and guard-let with C++ optionals.Scope: Only affects the C++ standard library overlay.
Risk: Low, this only has an effect if C++ interop is enabled and the C++ stdlib is used from Swift.
