> what I really want is secure subset of c++, enforced by compiler with hardened standard library(that is sanctioned by standard body, might be not 100% compatible with generic one, because it contains only a subset of functionality and some functions might work differently). Problem with this is, that your code would use such subset, but what about libraries you use ? Then you would have confusion as to which libraries are safe to use in such new C++, would they work with the standard C++ ? You would effectively have 2 languages inside of one. Remember all the C/C++ confusion and how compatibility to C has kept it back? That would lead to similar problems.
