This clarified - thanks - I'm wondering if it's safe to assume that the C++14 library is a superset of the C++11 one: in that case passing -std=c++14 would also automatically define the C++11 macro and I see a tiny front-end patch going in followed by smooth progress in library. Otherwise - if -std=c++14 does *not* automatically define the C++11 macro too - we also need a ton of boring changes in the library, where things become wrapped in C++11 macro || C++14 macro. Did I explain myself clearly enough?
