This person wants to add even more stuff to C++ :-) That's a bit crazy. But the article may interest someone, its about ways to add dynamic ways to C++, as partially done in C#4 and in a different way as done in Object-C (and the probably uncommon Object-C++):

In theory most of those things can be done improving the run-time reflection of D.
