In the current implementation, yes. But I think it's a bad idea to rely
on that, since a future implementation might no longer do this. (E.g.,
if we use a different hash collision resolution algorithm that is
sensitive to insertion order.)

It is probably safest to make an array of keys with .keys, and sort the
array in the order you want.
