Enhancements to C++ for writing better code

The programming language universe has changed a lot in the last decade and those changes should reflect in the  C++ programming language in its new avatar. Most of the innovations in Modern C++ involve handling advanced abstractions and the introduction of functional programming constructs to support language level concurrency. Most modern languages have got a garbage collector and a run-time manages these complexities. The C++ programming language does not have automatic garbage collection as part of the language standard. The C++ programming languages with its implicit guarantee of Zero cost abstraction (you do not pay for what you do not use) and maximum run-time performance, has to resort to a lot of compile-time tricks and meta programming techniques to achieve the abstraction level supported by a language such as C#, Java...
