manpagesynopsis()
bf(#include <bobcat/reverse>)nl()
manpagedescription()
Not all data types offering (or implicitly providing) iterators also offer
tt(reverse_iterators). Arrays don't, and neither do
tt(initalizer_lists). Pointers to array elements can be used instead of
iterators, but arrays cannot be used in range-based for-loops. The tt(Ranger)
class (cf. bf(ranger)(3bobcat)) can be used for defining tt(begin) and tt(end)
members allowing the use of arrays in range-based for-loops. Using bf(Reverse)
objects and data structures can be used in range-based for-loops and/or to
obtain reverse-iterators to visit data elements in reversed order.
The class template tt(Reverse, ReverseArray,) and tt(ReverseSize) are
normally not directly used, but are returned by the various tt(reverse)
support functions. These three classes offer two members tt(begin), returning
a tt(reverse_iterator) to the end of the data range of the object passed to
tt(reverse) and tt(end) returning a tt(reverse_iterator) to the beginning of
the data range of the object passed to tt(reverse).

itemization(
itb(reverse(Type &object))
returns a tt(Reverse) object offering reverse iterators to the data
range of tt(object), which must support tt(begin) and tt(end)
members. If tt(Type) is a constant type, then tt(Reverse's begin) and tt(end)
members return tt(const_reverse_iterators), otherwise tt(reverse_iterators)
are returned;
itb(reverse(Type (&array)[size]))
returns a tt(Reverse) object offering reverse iterators to the
reversed range of elements of tt(array). If tt(Type) is a constant type, then
tt(Reverse's begin) and tt(end) members return tt(const_reverse_iterators),
otherwise tt(reverse_iterators) are returned;
itb(reverse(Type *array, size_t size))
returns a tt(Reverse) object offering reverse iterators to the
reversed range of elements of tt(array) to tt(array + size). If tt(Type) is a
constant type, then tt(Reverse's begin) and tt(end) members return
tt(const_reverse_iterators), otherwise tt(reverse_iterators) are returned.
