What once required arcane template metaprogramming with <code>std::integral_constant</code> and recursive template instantiations can now be expressed using familiar <code>constexpr</code> functions that look almost like regular code. Three libraries represent different points on this spectrum: <strong>Boost.Hana</strong> for type-level metaprogramming, <strong>Frozen</strong> for constexpr data structures, and <strong>CTRE</strong> for compile-time regular expressions.</p>
