We can't wait that long when committee will accept std::optional. Are you sure it would get into c++14? I'm not. Next, when will MSVC support c++14? It still has no support for constexprs and unicode literals, AFAIK. More, Qt has to support ancient stuff like WinCE which is only supported by studio 2008. _______________________________________________ Development mailing list [email protected] http://lists.qt-project.org/mailman/listinfo/development
