I prefer the following modification, because it makes it easy to be a 
voyeur in method chains.

irb(main):001:0> module Kernel
irb(main):002:1>   def my_p
irb(main):003:2>     p self
irb(main):004:2>     self
irb(main):005:2>   end
irb(main):006:1> end
=> nil
irb(main):007:0> %w{a b c d}.my_p.collect{|i|'<'+i+'>'}.my_p.reverse
["a", "b", "c", "d"]
["<a>", "<b>", "<c>", "<d>"]
=> ["<d>", "<c>", "<b>", "<a>"]
