This small extension to ruby's Array class provides two additional iterators, Array#each_with_floe and Array#each_with_index_floe, that simplify the reasonably-common need to specially handle "floe"--i.e., first, last, odd, even--when iterating through the elements of an array. It's particularly handy for generating CSS classes.
