Hi, I recently answered a question on StackOverflow about set iteration order which made me read the spec.
I remember the recent "Set.prototype.entries: indices as keys" discussion but I couldn't figure out if the fact sets and maps are ordered on insertion order is specified is intentional and an artifact. The spec looks crafted in a way it looks intentional, for example in set: - Set.prototype.add always adds to the end of the entries list - Set.prototype.delete does not delete from the list but rather sets the value to `empty` - Iteration in %SetIteratorPrototype%.next iterates entries by index and in order. Am I understanding this wrong or is set iteration order specified (same for map)? Can anyone please refer me to previous discussions on this when the decision was made? I can't seem to find the relevant material and I'm interested in the rationale. Thanks again! Benjamin
