You can dup the module:

   module A
     def x
       puts "A"
     end
   end

   module B
     def x
       puts "B"
     end
   end

   obj =3D Object.new
   obj.extend(A).x          # A
   obj.extend(B).x          # B
   obj.extend(A).x          # B
   obj.extend(A.dup).x      # A

I'm not sure whether there are hidden pitfalls to this, perhaps
involving constants.
