I was mentoring these kids writing some code in C++ and I saw they were using all this syntax and functionality that was familiar from other languages, but that I had no idea was in C++. You see I used to program on games in C++, but like twenty years ago. I have learned a lot of languages since then, and don't really have a reason to go back to C++ although I liked it fine as a language. But it is possible to write C++ now that is really alien to me.
