Better C++14 reflections
summary
Claims a working C++14 reflection solution that needs no macros or external tooling and ships as Boost.PPR (GitHub). Implements auto ostream, comparisons, hashing and serializers by deriving field count via aggregate initialization, using an ubic conversion trick and a compile-time binary search to get logarithmic instantiation depth. Also shows a recursive approach and a loophole friend-function trick (MSVC/GCC/Clang support) and notes a much simpler C++17 structured-binding solution but with better compile-time performance tradeoffs.
