I'm thinking something like (untested):

   module M
     def join
       "I'm a new version of join!"
     end
   end

   arr = [1,2,3]
   Array.import_module(M) do
     puts foo.join           # I'm a new version of join!
   end
   puts foo.join             # 123

so that you'd be temporarily layering different versions of the
method(s).
