neither of these desugarings is perfectly in alignment with the actual spec.
which doesn't actually use a temp variable in this manner.
A closer match would be:
$$lastIteration_i = i;
$$lastIteration_i++;
The value of the new i for the next iteration is the incremented value of the
previous i, but the value of the previous i is not incremented which is
important for the cases where a closure has captured the previous i.
