In the "for fun" spirit, here's the boost::bind equivalent:

    string& (string::*assign)( string const & ) = &string::operator=;

    std::for_each(
        begin, end,
        bind( Print,
            bind( &std::string::c_str,
                bind( assign, string(), bind( &A::name, _1 ) )
            )
        )
    );
