singleton_meta_object(cls)

Class decorator that transforms (and replaces) a class definition (which must have a Singleton metaclass) with the actual singleton object. Ensures that the resulting object can still be “instantiated” (i.e., called), returning the same object. Also ensures the object can be pickled, is hashable, and has the correct string representation (the name of the singleton)
