I personally don't like the .first() .last() method implementation, this
means we'll have .second .third, etc... Why not just check the var iterator
$# == 0, means the first iteration, or have a special var that is not set to
the index, but rather the iteration number 1..end, in case the there is a
way to start iteration at different points.
