Ahh, lightbulbs are going off all over the place here :-) 

Java has nothing analogous to Class instance variables so i've be
using class variables like statics. But classes are Objects, so why
not treat them likewise. You can even have real singletons in Ruby,
unlike Java where a singleton is unqiue to a ClassLoader.
