Class Level Methods, how does THAT work?!

attr.rb

  tracked_attr_accessor :something
  
  def self.tracked_attr_accessor(*methods)
     methods.each do |method|
        attr_reader method
        self.define_method("#{method}=") do |arg|
          if method != arg 
            updated_fields << method
            instance_variable_set("@#{method}", arg)
          end
        end
      end
    end
