thanks all. that's how i explained it. i didn't quite get why the value of
$i remained the same (whatever it's initial value was)...until:

$i is incremented. Then $i is set with the old (pre-increment) value of
$i (++ has precedence over =).

thanks jerry. it just snapped for me. it's that even though $i++ may
increment, the lhs assignment is made from $i's initial value prior to the
increment... it's the = that resets/nullifies the ++ in this case. that
about right?
