WOW Coool :-)

but there is one thing i wonder about:
php -r '$ar=array(1=a,2=b,3=c);foreach($ar as $k=$v) if ($k==2) unset($v); 
print_r($ar);'
Array
(
[1] = a
[2] = b
[3] = c
)

I guess the main question is what should happen? I'd expect the result to be
$ar[2] = NULL since obviously you can't unset $ar[2] this way. (I tried this
because in SPL you can).
