Hello

Netbeans warns me with a little yellow alert sign on the left side that the following code is considered suspicious. When I put the mouse over the alert sign it says "Variable does not seem to be used in this scope". I like this check as it helps spotting typos in variable names but this time it is certainly on the wrong track. It underlins the $i in the foreach statement although that variable gets used as a object reference one line below:

    class T {
	public $attr = 42;

	public function f() {
            $a = array(new T(), new T());
	    foreach ($a as $i) {
	 	echo $i->attr;
	    }
	}
    }

The bug does not occur in every foreach nor if I move the foreach out of the class.
