I think we definitely want them to use the same protocol. .map() is appealing, but to work with for-of statements, it would have to support break, continue, and early return, either using exceptions (like Scala's Breaks) or something new. Part of the appeal of the iterator protocol is that it doesn't complicate break/continue/return. Separately, for the list: are arrow-functions lexically transparent to super and arguments? I hope so! For this kind of desugaring, if nothing else. -j
