Now that REALbasic 2006 has shared methods and shared properties,
is it possible to have a true Singleton object?
Sure -- but then, it was quite possible before too, except that the
enforcement was at runtime rather than at compile time.
The current shared methods and properties make the class behave like
a module, not like an object (which is what a singleton should be).
You can't store a reference to a class in a data structure, or
exploit polymorphism with its shared methods.
I have put in a feature request: bzvggysz for first-class classes.
Feel free to sign on.
