 This is not really what you do

pigeon% ruby -e 'a = [1,2]; b = [1,1,2]; p [a,b].max'
[1, 2]
pigeon% 

pigeon% ruby -e 'a = [1,2]; b = [1,2,1]; p [a,b].max'
[1, 2, 1]
pigeon% 

D>        short.each do |el|

D> 	   long.delete_at long.index(el)
D> 	 end
D>        end
D>        long
D>      end
D>   end
