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
