OTOH, GCC and Clang provide warn_unused_result, and it's easy to define types for returning errors from functions that throw a compile-time error if ignored by the caller. I find explicit error handling safer and more elegant than exceptions, especially if you consider that writing exception-safe generic code is hard and error prone.
