Subject: Re: CompareByValue

Curiousity struck me some and I discovered what I
posted wasn't the minimal set to make all tests pass.  I could
comment out two more lines without making the tests break:

module CompareByValue
  def ==(other)
    # return true if self.id == other.id
    return false unless self.type == other.type
    return false unless self.instance_variables == other.instance_variables
    self.instance_variables.each { |name|
      next if self.id == self.instance_eval(name).id
      next if self.id == other.instance_eval(name).id
      # next if other.id == other.instance_eval(name).id
      # next if other.id == self.instance_eval(name).id
      return false unless self.instance_eval(name) ==
        other.instance_eval(name)
    }
    true
  end
end
