<h1>Post-C++14 TS Implementation Status</h1>
<!--*********************************************************************-->
<p>In April 2013, the C++ standard committee approved the draft for the next version of the C++ standard, known as "C++1Y" (probably to be C++14)</p>
<p>The draft standard includes papers and issues that were voted on at the previous three meetings (Kona, Portland, and Bristol)</p>
<p>This page shows the status of libc++; the status of clang's support of the language features is <a href="http://clang.llvm.org/cxx_status.html">here</a>.</p>

[libcxx] Add <experimental/tuple> header for LFTS. Summary: This patch adds the `<experimental/tuple>` header (almost) as specified in the latest draft of the library fundamentals TS. The main changes in this patch are: 1. Added variable template `tuple_size_v` 2. Added function `apply(Func &&, Tuple &&)`. 3. Changed `__invoke` to be `_LIBCPP_CONSTEXPR_AFTER_CXX11`. The `apply(...)` implementation uses `__invoke` to invoke the given function. `__invoke` already provides the required functionality. Using `__invoke` also allows `apply` to be used on pointers to member function/objects as an extension. In order to facilitate this `__invoke` has to be marked `constexpr`. Test Plan: Each new feature was tested. The test cases for `tuple_size_v` are as follows: 1. tuple_size_v.pass.cpp - Check `tuple_size_v` on cv qualified tuples, pairs and arrays. 2. tuple_size_v.fail.cpp - Test on reference type. 3. tuple_size_v_2.fail.cpp - Test on non-tuple 4. tuple_size_v_3.fail.cpp - Test on pointer type. The test cases for tuple.apply are as follows: 1. arg_type.pass.cpp - Ensure that ref/pointer/cv qualified types are properly passed. 2. constexpr_types.pass.cpp - Ensure constexpr evaluation of apply is possible for `tuple` and `pair`. 3. extended_types.pass.cpp - Test apply on function types permitted by extension. 4. large_arity.pass.cpp - Test that apply can evaluated on tuples and arrays with large sizes. 5. ref_qualifiers.pass.cpp - Test that apply respects ref qualified functions. 6. return_type.pass.cpp - Test that apply returns the proper type. 7. types.pass.cpp - Test apply on function types as required by LFTS.
