| * [*Precondition:] The `value_type` of the range is an instantiation of `std::pair`. |
| * [*Postcondition:] For all elements `x` in the returned range, `x` is the result of `y.second` where `y` is the corresponding element in the original range. |
| * [*Range Category:] __single_pass_range__ |
| * [*Range Return Type:] for constant ranges, `boost::select_second_const<decltype(rng)>` otherwise `boost:select_second_mutable<decltype(rng)>` |
| * [*Returned Range Category:] The range category of `rng`. |
