 Certain data types, such as the C++ Standard Library's forward and bidirectional iterators, do not provide addition and subtraction via `operator+()` or `operator-()`. This means that non-modifying computation of the next or prior value requires a temporary, even though `operator++()` or `operator--()` is provided. It also means that writing code like `itr+1` inside a template restricts the iterator category to random access iterators.

 The distance from the given iterator should be supplied as an absolute value. For example, the iterator four iterators prior to the given iterator `p` may be obtained by `prior(p, 4)`.

 First, `boost::next()` and `boost::prior()` are compatible not only with iterators but with any type that provides arithmetic operators `operator++()`, `operator--()`, `operator+()`, `operator-()`, `operator+=()` or `operator-=()`. For example, this is possible:
