Pay attention that Singleton should not be about access but time. If you can by adding on instance variable avoid to need a singleton then it means that it was not a singleton. A singleton is often: you **CANNOT** have two instances at the same time. Many people do not use well singleton so watch out.

Is there a trait to quickly create singletons in Pharo, along the way of the Ruby Singleton mixin?
