static_assert(is_scoped_enum_type(^^int) == false);
class A {};
static_assert(is_scoped_enum_type(^^A) == false);
enum B { self_test = is_scoped_enum_type(^^B) };
static_assert(is_scoped_enum_type(^^B) == false);
static_assert(!self_test);
enum struct C { final, import, module };
static_assert(is_scoped_enum_type(^^C) == true);
enum class D : int { pre, post, override };
