I vote for C++ exceptions. That is why they are there.

If you always pass by reference, this isn't a problem. In C++, there is
almost never a compelling reason to pass objects by value. Always using
references is nice because you can tell by looking at the prototype
whether the argument is optional (if it's a pointer, it's optional). If
you always use pointers you have to read the documentation to find out.
