If you’re an experienced C++ programmer and are anything like me, you initially approached C++11 thinking, “Yes, yes, I get it. It’s C++, only more so.” But as you earned more, you were surprised by the scope of the changes. auto declarations, range-based for loops, lambda expressions, and rvalue references change the face of C++, to say nothing of the new concurrency features. And then there are the idiomatic changes. 0 and typedefs are out, nullptr and alias declarations are in. Enums hould now be scoped. Smart pointers are now preferable to built-in ones.
