Like I avoided ranged version of for before I have noticed we already use it. I've seen comments about lack of atomic for Windows in debug shared_ptr implementation, and also we wrap things like mutex, condition variable, etc... For future: Are there any clear guidelines what feature set form C++11 is safe to use? Or we shouldn't limit ourselves until someone starts screaming out laud? Cheers, /Piotr
