Ah, ok, missed that.

No, with 'iterated' you can't do that, as it will fetch an object at the time from the PHP driver (like with mysql_fetch_row()), so Datamapper doesn't know what 'first' and 'last' is.

As you correctly observed, the iterated variant is really useful when you have large datasets to you have to process sequentially, but if your datasets are small or you need random access, don't use it.
