This provides flexibility to clients that do not want to subclass a Rule but
still want to work with the rules library.
$rule = new Closure(function ($a, $b) { return $a === $b; }), array(1,2));
$rule->applies();//returns false: 1 is not equal to 2
public function testClosureRuleFalse()
{
$closure = function ($a, $b) {
return $a === $b;
};
$rule = new Closure($closure, array(1, 2));
$this->assertFalse($rule->applies());
}
