 When overriding a method multiple times by extending the object with a
 module, it seems that the last method lookup path is cached, or something
 among those lines.

 {{{
 class X
 end

 module Vegetarian
   def bananas
     "are so awesome!"
   end
 end

 module Carnivore
   def bananas
     "Carnivores #{super}"
   end
 end

 x = X.new
 x.extend(Vegetarian)

 puts x.bananas
 puts x.bananas

 x.extend(Carnivore)
 puts x.bananas
 puts x.bananas
 }}}

 Running the above results in:

 {{{
 are so awesome!
 are so awesome!
 Carnivores are so awesome!
 are so awesome!
 }}}
