Yes, you can use C++11 in your application. Our viewpoint is that Qt 
developers should be able to use C++11 internally in the project. They 
are slated to allow most of C++11 like decltype, rvalue references, and 
lambdas in 2016. However, things like constexpr will still not be allowed.

More importantly, there are many features of C++11 you cannot use in 
your application like smart pointers. Ok, you can use them, but you 
cannot use them to interact with Qt. To a modern C++ programmer this 
comes across as a significant limitation.
