ActiveSupport::ArrayExtensions::first()
- should return the first item of the passed array

ActiveSupport::ArrayExtensions::last()
- should return the last item of the passed array

ActiveSupport::ArrayExtensions::extract_options()
- extracts the last element from the array and returns it if it's an associative array

ActiveSupport::ArrayExtensions::is_associative()
