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

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