Problem: - There is no algorithm that does `for_each` on a range except for the last N elements. - There is a use case for a tripartite operation on a range: one operation for the initial element, another operation for each medial element, and a third operation for the final element. - The return values of `for_each` and `for_each_n` do not follow the law of Useful Return. Solution: - Add `for_each_butlastn`, `for_each_butlast`, and `initial_medial_final`. - Return all useful information from `for_each` and `for_each_n`.
