Yes, make sense like that.
I'm not sure what to do about the iterator when is on an invalid item, if you
reach an invalid item doing to_next should be possible to do to_previous to
recover the last valid item? Or is better to force the user to use to_last to
go back?
In some cases implement to_previous will need to store the previous item
(actually I did that on the patches I sent).
