You just need a class variable #UniqueInstance and those methods:

Wouldn't a class instance variable be better? I want new singletons for every subclass. http://rmod-pharo-mooc.lille.inria.fr/MOOC/Slides/Week3/C019-W3S03-Basic-Variables.pdf

I would also have used super new, why BasicNew? But my wish to create subclasses seems to answer that already.��

Thanks for your find-grained example, Cyril!
