Peter, you've annoyed Robert - he won't help you now ;-)

If you go to the trouble of calling a method, you may as well
do something with its return value rather than just losing it.


module Debug
  def who_am_i
    'Debug'
  end
end

module Burp
  def who_am_i
    'Burp'
  end
end

module Throb
 # #def who_am_i
 # #  'Throb'
 # #end
end

class EightTrack
  include Burp
  include Throb
  include Debug
  def who_am_i
    wai = [self.class]
    ( self.class.ancestors - [Object, Kernel] - wai ).each do |a|
      ( wai << a.instance_method(:who_am_i).bind(self).call ) rescue nil
    end
    wai
  end
end

et = EightTrack.new

p et.who_am_i  # [EightTrack, "Debug", "Burp"]
