No, using a class var there was totally appropriate.

In the case of your design, depending on what you're actually trying  
to accomplish by registering every instance, you can forgo the  
registration hash and use:

   ObjectSpace.each_object(YourClass) { |obj| ... }

That only iterates live objects and also has the disadvantage of not  
working in jruby or rubinius (yet?).
