Teaching old compilers new tricks
summary
Claims a working preprocessor called clang from the future that uses libclang AST transforms to transpile C++14/17 features into C++11 source so legacy compilers can compile them. Implements structured bindings, binary literals, digit separators, fold expressions, if constexpr via generated explicit template specializations and rewrites, integrates with make and CMake integration, and even emits object files for embedded toolchains (demo on an ESP32 object file). Prototype exists; production version is proprietary; debug-info roundtrips are planned but not yet implemented.
