I used to code C++ in early 00s and used to think I know the language OK. Then I stopped using it, meanwhile C++11 and friends came, along with lambda syntax, move semantics etc. - that was a jump but I could still just about follow.
Now I don't follow anymore. It's a new language on top of new language on top of new language. On top of C++. On top of C.
