[Pharo-dev] About the singleton pattern

Hi, We use quite often the singleton pattern but when I need to use one, I always need to ask myself "What is the selector to get this singleton?". We use either aClass>>current, aClass>>default or aClass>>uniqueInstance. Could we agree on the selector to use and update existing code? To get a quick overview, I searched about these methods in a Pharo4 image and get these results: ((SystemNavigation default allImplementorsOf: #default) select: #isMetaSide) size. "45" ((SystemNavigation default allImplementorsOf: #current) select: #isMetaSide) size. "40" ((SystemNavigation default allImplementorsOf: #uniqueInstance) select: #isMetaSide) size. "19" Your opinion? Christophe.
