MSVC C++23 Conformance
summary
MSVC claims concrete C++23 work: modules and modules available in C++20 mode so code can use module exports without switching language version, implementation of the multidimensional array operator and size_t literal suffix _uz, and new library pieces like mdspan and std::print plus automatic range formatting and an empty-line helper. Compiler adds MSVC_STL_HARDENING=1 (off by default) for UB checks, supports deducing this with modules, static lambdas, and uses if consteval to emit SIMD runtime paths while allowing compile‑time fallback.
