There was a problem hiding this comment.
This really just causes the error to cover the iterator exhaustion case for next and so is somewhat of a bad test, but we'd need to add a custom exception here otherwise and I'm not sure if that is worth it.

I'm ok with the test looking like this, since this doesn't necessarily mean an impact in actual user-facing code. |
