tuple＜＞: What's New and How it Works
summary
Covers concrete C++ tuple changes and how they’re implemented: get-by-type (C++14) and conditionally-explicit constructors (C++17) change overload and initialization behavior; std::conjunction/disjunction short‑circuit trait checks to avoid ill‑formed instantiations; integer_sequence + index_sequence power efficient variadic unpacking and enable the mini‑binder example that calls functions from stored tuples. Implementation detail: Visual Studio uses a make_integer_sequence compiler hook for speed; apply and make_from_tuple are specified in C++17 (make_from_tuple uses parentheses, not braces). Some features land in VS2015u3; others expose front‑end bugs found during testing.
