But I am. I have seen it when switching from one MSVC version to another, and with Intel compilers as well. My impression is that compiler vendors try to remove more and more of these unwanted dependencies from version to version. Especially gcc was known to pull in many unneeded includes, so it is good that they reduce them. > For example, the docs say that the <algorithm> header is required for > std::count.
