That's not so great if you call library routines that can raise exceptions, and having to propagate error values back up the call chain is precisely the hassle that exceptions avoid. There is a proposal for "deterministic exceptions" in C++ that work like Haskell's Either monad. I.e. they are syntax sugar for propagating error values upwards, with the compiler automatically inserting the tests so you don't have to manually check the return values everywhere. I guess they are a good idea but I don't know if they can replace the other kind of exceptions. I don't know the current state of the proposal but some info and links should be here: https://github.com/cplusplus/papers/issues/310
