> One thing I was surprised not to see mentioned here is multiple inheritance. There's nuance to banning that since implementating multiple interfaces is technically multiple inheritance in C++. So I think I'd agree with you but with an exception for pure-virtual classes. > Also, while iostream is a bit of a mess, having it be strongly typed means that it's, in my opinion, well worth using over cstdio. Orthodox C++ would ban this but you can have both printf-style with type safety with https://github.com/fmtlib/fmt https://github.com/fmtlib/fmt Which inspired C++20's std::format: https://en.cppreference.com/w/cpp/utility/format https://en.cppreference.com/w/cpp/utility/format Which is also banned by Orthodox C++
