You really have to look at the source code in delegator.rb.
Instantiation creates a singleton method for all forwarded
methods - However some methods are not forwarded
(preserved) for example when they already defined in the
Delegator sub class. Now combine this with the following
behavior
---
module A
  def foo
    "subordinate"
  end
end

class << a = Object.new
  def foo
    "dominate"
  end
  include A
end

p a.foo # dominate
--
and you have your explanation
