I think it's more future-looking to allow pickle round-tripping.
I tend to agree.
Just add a ._uuid attribute and have object equality follow equality of that attribute. There's no reason to expose that in the .__repr__, but it would be inspectable in concept.
I think it's worth preserving the idiom of comparing sentinels using `is`, as we do for `None` and other existing sentinel values. It's relatively easy to do, such as by using a single-value Enum or by using a class with a custom __new__. - Tal
