And developers never forget to check error codes.

Looking at code, it‘s easier to spot the missing check for an error code, than a not catched exceptions.

Also error codes are part of the signature of a function, which exceptions aren‘t.

If you need to wrap each call in try/catch, it's better to use return codes in some form or rethink the approach.

may I introduce you to the nodiscard attribute[1]?

  enum (class)? [[nodiscard]] Error {
    Ok,
    NoMem,
    ...
  };
