Why not just modify the Lines iterator to return values of IoResult<~str>? All the caller has to do to unwrap that is to use if_ok!() or try!() on the returned value, so, its basically just as easy to use and it means that errors are handled consistently. I don't see why this particular use case calls for a completely different error handling strategy than any other IO code.
