Perhaps something like...:

class metaSingleton(type): def new(cls, classname, classbases, classdict): result = type.new(cls, classname, classbases, classdict) if classbases: return result() else: return result

By the way, there's a bug in the above implementation: it can't be safely mixed with other metaclasses, because it calls 'type' directly instead of using 'super()'.
