Rails - May 2006 - each_with_index. Can you start at a desired index position?

When using array.each_with_index how do you start at a desired index 
position?

I can do it like this, but its not very clean and doesnt seem efficient 
:

desired_index_start = 20
array.each_with_index do |value,index|
  next if index<desired_index_start
end

Thanks
Chris

Here''s one way.

array[20..-1].each_with_index do |value,index|
  ...
end
