Except that they don't. :-P We don't want has_next and has_previous but something more like "has current", (perhaps to pair with get_current?). > The only downside is that the function names are a bit long in some > cases, but I'm willing to live with that until someone comes up with > better. One option is to just drop the "move_ " prefix. Then everything will be a two-word function. So the new proposal is: to_first has_current to_next to_last has_current to_previous get_current Better? -Carl
