A Tale of Two Tuples - A Story of the C++ Revolution
summary
Claims a rule-of-zero tuple that omits all special member functions and a lambda-tuple access style map to implement get, tie, swap and streaming with no temporaries. Delivers an open source Tuple library plus a C array helper, expanded by preprocessor to 16 elements (tested to 64), uses C++20 no_unique_address and structured bindings, exposes portability issues with no_unique_address, and admits tuple_cat caused CI breakage but core APIs work for regular applications.
