Not sure if I understand that. Let's see if I understand well. move_to_first (or move_to_last) will put the iterator in the first (or last) valid item. move_to_next (and move_to_previous) will be able to reach an invalid item outside the list. Is it like that? In some implementations of iterators (like C++ STD) you can reach invalid i= tems only in one side of the list, at the end, but not at the beginning. Some pe= ople get use to this idea, but should not be a big deal to do it different. So you are thinking in a function has_current showing if the current item is valid.

I think that's a good option. The names of the functions are still clear li= ke that, and the original names are too long.
