===== Ongoing hierarchical list of new C++11 features =====

Constantly being shuffled around; this list will be used as the basis for the more specific pages listed above.

==== Misc fixes ====

  * right angle brackets

==== Data types and literals ====

  * ''alignas''/''alignof''
  * ''decltype''
  * ''char16_t'', ''char32_t''
  * ''nullptr''
  * New string literals (Unicode, raw)
  * User-defined literals
  * ''auto'' type deduction
  * ''constexpr'' (here?)
  * type traits

Any other new character types?


==== General language features ====

  * Initializer lists
  * Overloading and "= delete" for non-member functions
  * Trailing return types (mostly for templates)

==== Looping ====

  * Range for loops
  * for_each, non-member begin() and end()

==== Namespaces ====

  * Inline namespaces

==== Enumeration types ====

  * scoped enums
  * forward enum declarations
  * strongly-typed enums (n2347.pdf)

==== Class "life cycle" methods ====

  * Delegating constructors
  * Inheriting constructors
  * Move semantics (tied to rvalues)
  * "''= default''"
  * "''= delete''"

==== Rvalue references ====

  * Basic rvalue references
  * Rvalue references for ''*this''

==== Class features ====

  * Non-static data member initializers
  * Explicit conversion operators
  * Extended friend declarations

==== Inheritance issues ====

  * ''override''

  * Extended friend declaration
  * Local and unnamed types as template parameters(?)



==== Lambda expressions ====

==== Exceptions ====

  * ''noexcept''

==== Debugging ====

  * static_assert()

==== Standard Library ====

  * With the approval of C++11, TR1 is officially incorporated into standard C++ standard, along with new libraries that have been added since TR1.
  * threading library
  * relies heavily on move semantics
  * New algorithms [[https://blog.smartbear.com/development/the-biggest-changes-in-c11-and-why-you-should-care/|here]]
  * tuple

==== Concurrency ====

  * async()

==== Others ====

  * extern template
  * Regular expressions
  * C99 preprocessor (''__cplusplus''??)
  * Unrestricted unions
  * Attributes
