alt Hacker NewsThinking about this upfront for me, I am actually wondering why this is useful outside of equality comparisons.
Granted, I live and work in TypeScript, where I can't `===` two objects but I could see this deterministic behavior making it easier for a language to compare two objects, especially if equality comparison is dependent on a generated hash.
The other is guaranteed iteration order, if you are reliant on the index-contents relationship of an iterable, but we're talking about Dicts which are keyed, but extending this idea to List, I see this usefulness in some scenarios.
Beyond that, I'm not sure it matters, but I also realize I could simply not have enough imagination at the moment to think of other benefits

Being able to parse something into a dict and then serialise it back to the same thing is a bit easier. Not a huge advantage, though.
I work on a build system (Bazel), so perhaps I care more than most.
But maybe it does all just come down to equality comparisons. Just not always within your own code.
