Subject: Modules, instance methods and class methods


  Hello !

  I have a rather tortured architecture where several classes should
share code for some class methods and for some instance methods. To fix
the ideas, I need that some class I define have:

def ThisClass.desc
  return @desc
end

def desc
  return self.class.desc
end

  To do that, I define two modules

module BaseInclude
  def desc
    return self.class.desc
  end
end

module BaseExtend
  def desc
    return @desc
  end
end

  and I include them with

class ThisClass
  include BaseInclude
  extend BaseExtend
end

  That works perfectly fine. My question, then, is : is there a simpler
way ? I can't afford to have a shared ancestor for these classes.

  Thanks !
