> The return values of functions returning std::expected types cannot be 
> discarded as the std::expected type is marked with [[nodiscard]] attribute in 
> the MSVC implementation. As we previously used nonstd::expected that did not 
> have any restriction. We should handle the return values of these functions 
> to avoid these warnings.
