TBH, I don't think it's right to have a Singleton class which is
subclassed by a bunch of different singletons. They aren't really
subclasses of the same class. I could imagine Singleton being a
metaclass, perhaps, but otherwise, they're not really similar to each
other.
I'm with you on this - should have made Singleton() an ABC.
Yes, would only be a skeleton around which concrete singleton classes
could be built.
Like you, I v.rarely use them - but which means that the ABC is useful
because it would save me from having to remember the curly-bits
all-over-again...
