@Campbell I am pretty sure give how hard Apple is pushing out new releases and given how many people upgrade that we can just assume an llvm/clang 3.0+ feature set for c++11.
I think we should also do this analysis for C99 support and C11 support. There are some other projects out there that use C++11 features (clang is one) and they have made comprehensive analysis of what features they can and do use. There are some things we can use anyway like noexcept provided we use it like the QT people use it so the code does not require a c++11 compiler but you do get some benefit from compiling with one ( http://qt-project.org/doc/qt-5/qtglobal.html#Q_DECL_NOEXCEPT) I think getting a sort of caniuse.com for c/c++ language features on the wiki would be good way forward.
