Subject: Re: Delegating class methods

I'm the OP. Thank you all for your replies.

Sorry if the question wasn't clear enough. I wanted to register all
the instances of a class, so the original idea was to use a hash class
variable to do that.

Of course there are a number of gotchas if you want to make the code
concise using this approach, so an alternative solution is to declare
another class, make it a Singleton and use it for that purpose.

I'm not a seasoned Ruby programmer, but I think I was totally right in
the idea of using class variables (@@hash). I cannot see why some
people are surprised. I'd be very happy if somebody could shed some
light on the issue, because maybe I'm missing something...
