This is a great test! But I feel like the example from Iterator::enumerate was a little clearer in its intent:
let a = ['a', 'b', 'c'];
let mut iter = a.iter().enumerate();
assert_eq!(iter.next(), Some((0, &'a')));
assert_eq!(iter.next(), Some((1, &'b')));
assert_eq!(iter.next(), Some((2, &'c')));
assert_eq!(iter.next(), None);Perhaps manually calling next().await might make it easier to follow?

LGTM -- going to leave it to @stjepang for the final review. We're two weeks out from needing to stabilize our full API so this might be held up for a little bit.
