If I know ahead of time I want a single element, it's just a waste of time to dereference an array element--granted, a rather trivial waste of time. In fact, it could be useful to enforce retrieval of a single element, for performance reasons if nothing else. I concede a conceit, though: I think accessing selectElements()[0] every time I want a single time is ugly. > I'd prefer an optional extra argument. Ugh ... I'd rather have just the one method and use selectElements()[0] than have an optional parameter for something like that. In all honesty, I'd be okay with just selectElements, plural. I can live with [0] notation. But I would appreciate having the option. I'm curious, Sander: what is the objection to having both? Dan
