Great idea! Why not just import the Rails code for dynamic finders into 
Ruby's Array, e.g.

   [1,2,3,4].get_second_and_third # => [2,3]

   [1,2,3,4].get_second_or_third # => [2] or [3] depending on random!!!

   [1,2,3,4].get_second_to_last # => [2,3,4]

This will produce much more readable sourcecode!!!
