On page 6, the startOfObject function template has a local class helper, which
has a member function template. Member templates are not permitted in local
classes. The code should read:

    namespace helper
    {
	template<typename T>
	static void* DoDynamicCastToVoid(T*p)
	{
	    return dynamic_cast<void*>(p);
	}
    }
	
    template<typename T>
    void* startOfObject(T*p)
    {
	void* result=static_cast<void*>(p);
	
	if(p)
	{
	    typeid(result=helper::DoDynamicCastToVoid(p),*p);
	}
	
	return result;
    }
