There is a std::reverse_iterator template that has been around
since C++98. In C++20 it is compatible with proxy iterators, and is constexpr- and noexcept-friendly.
If you are using C++20 or later, just use std::reverse_iterator.
For code built against earlier versions of C++, you can use reverse_iterator.
There's nothing much to document about it; it works just like std::reverse_iterator.
