Suppose I would want to have my own custom representation of "None".
What should I do to have my child class be a singleton too? (just extending singleton as well?)
None isn't a singleton. But have a look at the Null PMC or better env.pmc. $ grep singletion classes/*.pmc (the way to create singletons might change though)
thanks for your help, klaas-jan
