constexpr	wide ()=default
	Default-initialize the underlying array. Use wide{} for value initialization.
template<std::size_t I> requires (I < N)
constexpr T &	get () &noexcept
	Access element I, preserving constness and the value category of the pack.
template<std::size_t I> requires (I < N)
constexpr T const &	get () const &noexcept
	Access element I, preserving constness and the value category of the pack.
template<std::size_t I> requires (I < N)
constexpr T &&	get () &&noexcept
	Access element I, preserving constness and the value category of the pack.
template<std::size_t I> requires (I < N)
constexpr T const &&	get () const &&noexcept
	Access element I, preserving constness and the value category of the pack.
constexpr	wide () noexcept(std::is_nothrow_default_constructible_v< std::array< T, N > >)
	Retain opted-in array initialization in the element's target scope.

	Take an array of exactly the pack extent.

Detailed Description

template<class T, std::size_t N>
struct native::wide< T, N >

Own N values of T, including an empty pack when N == 0. registers is the underlying array. Tuple access and structured bindings refer to the actual elements. Value initialization follows T's rules; no general floating-point or zero-initialization policy is added here.
