[boost] [algorithm] adjacent_for_each interest?

Hi, Is there any interest in a version of for_each that operates on each adjacent pair of elements in a range? #include <iostream> #include <boost/algorithm/adjacent_for_each.hpp> void PrintInts(int a, int b) { std::cout << '(' << a << ", " << b << ")\n"; } int main() { const int ints[] = {0, 1, 2, 3, 4}; boost::algorithm::adjacent_for_each(ints, ints + 5, PrintInts); } Output: (0, 1) (1, 2) (2, 3) (3, 4) Initial implementation available at http://github.com/irh/adjacent_for_each Best, Ian
