Other Boost.Range metafunctions are defined by the following. Let `Range` be any type listed above and `Ref` be the same as `range_reference<Range>::type`. `range_value<Range>::type` is the same as `remove_reference<remove_const<Ref>::type>::type`, `range_difference<Range>::type` is the same as `std::ptrdiff_t`, and `range_pointer<Range>::type` is the same as `add_pointer<remove_reference<Ref>::type>::type`. As for `const Range`, see below.
