I assume `FrozenDict` always returns its elements in the same order when running `repr` on it?

I can make the unit test pass by swapping the order in which elements are inserted.

I’d expect behavior more like `FrozenOrderedSet` where insertion order does not matter.

Am I making an unwarranted assumption about `FrozenDict`?

(but the equality test should have returned `True` regardless of the order in which I constructed the data structure in question)

python dicts are always iterated in insertion order, as of 3.7: <https://softwaremaniacs.org/blog/2020/02/05/dicts-ordered/>

but they still compare equally even with different insertion orders:
```&gt;&gt;&gt; {"a": 0, "b": 1} == {"b": 1, "a": 0}
True```

we could just do `self._data _==_ other._data` I would have thought

And it sounds like that would be more correct
