std::experimental::ranges::Readable

定义于头文件 `<experimental/ranges/iterator>`
template< class In > concept bool Readable = requires { typename ranges::value_type_t<In>; typename ranges::reference_t<In>; typename ranges::rvalue_reference_t<In>; } && CommonReference<ranges::reference_t<In>&&, ranges::value_type_t<In>&> && CommonReference<ranges::reference_t<In>&&, ranges::rvalue_reference_t<In>&&> && CommonReference<ranges::rvalue_reference_t<In>&&, const ranges::value_type_t<In>&>;		(ranges TS)

Readable 概念由可通过应用 operator* 读取的类型满足，例如指针、智能指针和迭代器。
