Thoughts on adopting Python's for/foreach else construct.

I don't remember if this has been discussed before, but I've been working with some listing code and wishing for a cleaner way to do this <?php if (count($a) === 0) { // code for no results } else { foreach( $a as $key => $value) { // code for iteration } } ?> How difficult would it be to make the following work in the interpreter? <?php foreach($a as $key => $value) { // code for iteration } else { // code for no results } ?> The code of the else clause executes if the foreach is never entered regardless of the reason (provided the code didn't outright crash) Thoughts.
