I thought about @robsdedude arguments against introducing this and the one that resonated with me the most is: EagerResult has everything loaded in memory and Single is just a simple len(myEagerResult) == 1, so the added value is quite minimal.
On the other hand, Result does not have a known size and there is value in exposing Single which asserts there is exactly a single result left to consume.
