C++ Error Handling Revisited
summary
Shows a working plant-watering example that compares Haskell’s Maybe/Either and do/bind patterns with Rust’s Option/Result and C++17 features, using std::optional, std::variant and std::visit then replacing them with a small custom result type and a C++ bind operator. The custom wrapper noticeably cuts boilerplate and keeps descriptive value-returning APIs; implementing do-notation in readable C++ remains unresolved, but the homemade result plus bind proves practical and surprisingly simple.
