I can't think of a reason not to specify what ES5 does here (always
use the last one). This is a perfectly reliable way to write into a
hash table during decoding. And while you can't depend on a single
hash table's iteration order during encoding, you can count on unique
keys, so the appearance of duplicate keys in a JSON dictionary implies
a sequence of sets.
