Compatible with 1.8
Different only in 1.9:

class Module
  def method_added name
    puts "> #{self}::#{name}"
  end
end

module Kernel
  def singleton_method_added name
    puts ">> #{self}::#{name}"
  end
end


module M
  module_function
  
  def foo
  end
  
  p private_instance_methods(false).include?(:"foo")
  p instance_methods(false).include?(:"foo")
  class << self
    p private_instance_methods(false).include?(:"foo")
    p instance_methods(false).include?(:"foo")
  end
end
