    Thanks for the note on main! In fact, I could not find clause 999.9.9.9.9 of
    ISO/IEC 14882:1998(E). Did you mean 3.6.1.2?

    Now suppose I have 2 versions of a func in the base class: a const one and a
    non-const one. They are both private. Are both versions made public in the
    derived class if I add a using declaration in the public section of the
    derived class? If so, how do I make only one of them public?
