I am not sure I would call it novice use. Normally you simply want to
manipulate the object itself. As in:

class foo {
public $prop = 1;
}
$a = new foo();
$b = $a;
$b->prop++;
echo $a->prop;

This will of course output 2. Manipulating the object through any of
its references will be reflected in all the others as there is just one
object here.
