This article was originally published as a gist here. What is Orthodox C++? Orthodox C++ (sometimes referred as C+) is minimal subset of C++ that improves C, but avoids all unnecessary things from so called Modern C++. It’s exactly opposite of what Modern C++ suppose to be. Why not Modern C++? Back in late 1990 we were also modern-at-the-time C++ hipsters, and we used latest features. We told everyone also they should use those features too.
