What's the best way to add putsd as an alternative to puts to an app?

file.rb

module App
  module Debugable
  
    def putsd(msg)
      puts msg if ENV[DEBUG]
    end
    
    def self.putsd(msg)
      puts msg if ENV[DEBUG]
    end
    
  end
end


module App
  
  class Glass
    extend Debugable
    include Debugable
    
    def drink
      putsd "Glass is being drinked from!"
    end
  end
end


module App
  extend Debugable
  include Debugable
  
  DEBUG = "PARAMETER_DEBUG"
  
  def self.main
    putsd "Initializing with no parameters"
    
    glass = Glass.new
    
    glass.drink
  end
end



ENV['PARAMETER_DEBUG'] = 'true'
App.main
