Error-handling is probably the most divergent part of C++. Many coding guidelines partially allow exception or completely bans, and this leads to many projects supporting multiple error-handling interfaces, such as exceptions, error-prone c-style error-handling, and/or custom error-handling types. This video talks about STX; a C++ library that seeks to fix some of these issues with error and optional value handling in the C++ ecosystem and also seeks to unify some of these efforts/implementations.
