These new variants guarantee two specific behaviors:
The futures returned for each element of the iterated sequence will be executed singularly and strictly in order. Only one will run at a time, and the order in which they run will match that returned by the transformation callback.
If any one of the futures should fail, no other futures will begin execution, even if they were ready to do so.
