Then perhaps somebody should should lobby for a feature such that if a
    name is not found during lookup, it should be looked up again in
    the std namespace, and if it is found in the std namespace, the
    message 'The name xxx has been moved to the std namespace, as per
    ISO C++ 1998. Use std::xxx, or an appropriate using declaration.'
    should be appended to the error message.
