I like C++11 too. (My introductory book was on C++11 as well—yes, it’s that book about modern C++11.) But some projects require C++14, and other times I have to use C++98.

I’m a “traveling programmer” in Korea. But when I go out to a work site because they say I have to work on C++, as you know, there are so many versions that it’s painful.
