  # In Ohm v1.2, the Set initialize method is defined on
  # itself. Hence the trick of doing a module OverloadedSet
  # with an initialize method doesn't work anymore.
  #
  # The simplest way to solve that as of now is to duplicate
  # and extend the #initialize method for Ohm::Set.
  #
  # Granted it's not the _ideal_ way, the drawbacks are
  # outweighed by the simplicity and performance of this
  # approach versus other monkey-patching techniques.
