When access to an object's internals is truly necessary, it isn't practical to use composition based techniques. For example, consider the following mixin-based code which implements a memoization routine for caching method return values:

module Cached
  def cache(*method_names)
    method_names.each do |m|
      original = instance_method(m)

practicingruby

module Cached
  def cache(*method_names)
    method_names.each do |m|
      original = instance_method(m)
      results  = {}

      define_method(m) do |*a|
        results[[m, a]] ||= original.bind(self).call(*a) 
      end
    end
