Re: separate class that prepares an IteratorAggregate object for View layer - where to place this?

i see
you would probably need a global app controller behavior which
translates everything right away

php doesnt have the attributes itself
but you can acomplish that by using:
$size = count($cars);
$first = array_shift($cars);
$last = array_pop($cars);
and may others
etc
