Das Gut² Buch - constant

Cannot put at top because we need the full constant definition.

template <typename...> inline constexpr constant is_constant_v = constant_v<false>; template <auto C> inline constexpr constant is_constant_v<constant<C>> = constant_v<true>; } // namespace gut #include "constant.hpp" #if !__has_include("config.hpp") #error "All modules must include config.hpp." #endif using namespace gut; namespace {}
