I like the use of the keyword 'typename' instead of 'declare' for
this. So you can use it for standard library classes (and template
classes) as follows:

    typename std::runtime_error;

    extern bool IsFatal(std::runtime_error &);

    constexpr bool all_are_fatal = false;

    bool Process(std::runtime_error &arg)
    {
        return all_are_fatal || IsFatal(arg);
    }

In the future, perhaps the use of the typename keyword could be
extended, perhaps even to specify the mangled name of the type:

    typename SomeType "_Z8SomeType";
