What is your most surprising new feature in c++11?

For me, I was most surprised to add support for multithreading to the standard. Really want to be unclear, for a language like C + +. How could it be added to this thing.

1. Because of the different platforms, multi-threaded support will have many unique features of the platform. Such a definition of the C + + standard is bound to be very restrictive.

2. Various platforms have developed their own standards for multi-threaded support, such as Pthread. Or a standard API on Windows. Does it make sense to push the multithreaded standard for C + + today? Isn't it too late?

But I still see a lot of great feature in C++11.

It is believed that a very large number of feature will be in the future of C + + programming in a big way.
