Result back from the function in the Rule.

[yayabla]

Would be nice to have the result back from the function in the Rule.
not really an issue but it makes the Ruler more complete :)

$rb = new RuleBuilder;
$rule = $rb->create(
$rb->logicalAnd(
$rb['minNumPeople']->lessThanOrEqualTo($rb['actualNumPeople']),
$rb['maxNumPeople']->greaterThanOrEqualTo($rb['actualNumPeople'])
),
function() {
return 'YAY!';
}
);
$context = new Context(array(
'minNumPeople' => 5,
'maxNumPeople' => 25,
'actualNumPeople' => function() {
return 6;
},
));
echo $rule->execute($context); // "Yay!"

this does not work.
but if you change line in Rule.php;

public function execute(Context $context)
{
if ($this->evaluate($context) && isset($this->action)) {
if (!is_callable($this->action)) {
throw new \LogicException('Rule actions must be callable.');
}

        **return** call_user_func($this->action);
    }
