[QUOTE="Stefano Zacchiroli, post: 4545475"] Page 374. Note that the discussed topic is not "module instance variables", but rather the class << self trick for associating a class with the self object (which in the pickaxe case is a class object). AFAIU the same is done in the solution proposed to me, but with a module object instead of a class object. Correct me if my understanding is wrong. Cheers. [/QUOTE]
