One way of avoiding method ambiguity from multiple modules is to alias those methods.
An alias is a copy of an existing method with a new name.
You use the alias keyword followed by the new name and then the old name:
alias happytalk talk
You can use alias to make copies of methods that have been overridden so that you can specifically refer to a version prior to its overridden definition:
module Happy def Happy.mood return "happy" end# from w w w.j ava 2 s.c om def talk return "smiling" end alias happytalk talk end module Sad def Sad.mood return "sad" end def talk return "frowning" end alias sadtalk talk end class Person include Happy include Sad attr_accessor :mood def initialize @mood = Happy.mood end end p2 = Person.new puts(p2.mood) #=> happy puts(p2.talk) #=> frowning puts(p2.happytalk) #=> smiling puts(p2.sadtalk) #=> frowning
