Review comment:
Comparing dicts ignores order. Is that that's intentional?
```
>>> {1:2, 3:4} == {1:2, 3:4}
True
>>> {1:2, 3:4} == {3:4, 1:2}
True
```

Review comment:
I tried running this interactively but got the same hash:
```
>>> hash(type({}.items()))
5913863196444
>>> hash(type({1:2}.items()))
5913863196444
```
Is it working as intended?
I guess this is technically okay according to the docs, but probably not
what you wanted: `The only required property is that objects which compare
equal have the same hash value`.
[ref](https://docs.python.org/3/reference/datamodel.html#object.__hash__)
