The Iterator Helpers proposal defines 6 lazy synchronous iterator methods,
map, filter, take, drop, asIndexedPairs, and flatMap.
All of these methods are to return the newly defined builtin generators,
which we implement as self-hosted generators that are stored in an
internal slot and thus observably distinct from regular generators.
