I’m sorry, but all of this cool stuff is blowing my mind.

<pre><code>
class DwemthysArray < Array
  alias _inspect inspect
  def inspect; "#<#{ self.class }#{ _inspect }>"; end
  def method_missing( meth, *args )
    answer = first.send( meth, *args )
    if first.life < = 0
      shift
      if empty?
        puts "[Whoa.  You decimated Dwemthy's Array!]" 
      else
        puts "[Get ready. #{ first.class } has emerged.]" 
      end
    end
    answer || 0
  end
end
</code>

It takes a minute to grok, then… Whoa.
