#Did you know you can use reverse_each?

of course, there is even _each_ :)

but i am suggesting this:

x=[0,1,2,3,4,5]	=>[1,2,3,4,5]
x[-1..-6]	=>[5,4,3,2,1]
x[-3..-4]	=>[3,2]

right now, the above return empty [].

kind regards -botp

#
#x = (0..5).to_a
#x.reverse_each do |i|
#  print i
#end
##=> 54321
