Defined in header <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)

The concept Readable is satisfied by types that are readable by applying operator*, such as pointers, smart pointers, and iterators.
