I would like to suggest "try_emplace" for std::optional,

which works like the following:

template <typename T, typename ... Ts>

void std::optional<T>::try_emplace(Ts && .. ts)

{

  try

  {

    emplace(std::forward<Ts>(ts)...);

  }

  catch (...)

  {}

}

Main use case is optional components which we want to eat exceptions if they fail to initialize:

std::optional<logger> m_logger;

...

m_logger.try_emplace(logs_directory);

...

if (m_logger.has_value())

{

  m_logger->log(message);

}

else

{

  std::cerr << message << std::endl;

}
