The thing is I don't need the next item. I need to know if the

Write a one-ahead iterator class, which I have posted before, that sets
.exhausted to True when next fails.
And hope that the generator doesn't have side-effects...
If run to exhastion, the same number of side-effects happen.
The only difference is that they each happen once step happpen sooner.
For reading a file that is irrelevant. Much else, and the iterator is
not just an iterator.
