If I use a strict subset of C++, probably will do. However, figuring out the subset of different C++ standards and implementation that doesn't include extra pointers is hard. I might need to re-implement some useful utilities like unique pointer and share pointers as well. Some fundamental data structure in C++ includes pointers as well, like short string optimization introduce extra pointers. With my poor C++ knowledge, I don't even know what are the other pointers are missing..
