If I iterate over `(key,value)` pairs in `Dict`, or `keys(dict)`, or `values(dict)`, using _multiple iterations_, but _not modifying the dict between iterations_, is it guaranteed that I get the objects in the same order? (which is “random”, but I don’t care as long as it is consistent).
Looking at the implementation, this seems to be so, but I don’t know if this is something I can rely on (could not find it in the documentation).

Yes. The underlying storage arrays are only resized/rehashed when the contents of the Dict itself are modified.
Cheers!

But that’s actually an implementation detail of `Dict`, and not necessarily guaranteed in the future, IIUC.
But see [https://github.com/JuliaLang/julia/issues/20678](https://github.com/JuliaLang/julia/issues/20678)

Probably the best method (at least semantically) would be to convert the Dict into an OrderedDict (from DataStructures), this would freeze the order for later usage.

That’s what I thought. It would be nice to have that guarantee though, perhaps as a trait for some types.

Since I am only using it a few times, and always linearly after I finished accumulating values, it turns out that collecting and working on that is the fastest solution.
