One more (was Re: [PHP-GTK] Assignment evalution weirdness)

In the same context, e.g. in a method from a class extending
GtkWindow:

	// we assume $this->hash = array();

	var_dump( $this->hash[ 'foo']);	// NULL
	$test = $this->hash;
	var_dump( $test[ 'foo']);	// NULL, too, its ok

	if( isset( $test[ 'foo'])) {	// works, doesn't enter the if

	// but

	if( isset( $this->hash[ 'foo'])) { // enters the if here
