using size_type = size_t;
using iterator = const E*;
using const_iterator = const E*;
constexpr initializer_list() noexcept;
constexpr size_t size() const noexcept; // number of elements
constexpr const E* begin() const noexcept; // first element
constexpr const E* end() const noexcept; // one past the last element
};
// initializer list range access
template<class E> constexpr const E* begin(initializer_list<E> il) noexcept;
template<class E> constexpr const E* end(initializer_list<E> il) noexcept;
