It works ok if you do the conversion to the base class explicitly:

      for (int x: static_cast<std::vector<int>&>(*this)) { }

I think the range-for code needs to do overload resolution in the class' scope,
but it fails to and tries to say the begin/end members are protected, then gets
into trouble while trying to print the error message.
