Re: [fw-mvc] autoloader issue with reflection class

newInstanceArgs distribute the elements of an array to the parameters of
__construct().

$args = array('a','b');
class A {
public function __construct ($first, $second) {
echo $first;
echo $second;
}
}
$r = new ReflectionClass ('A');
$r->newInstanceArgs ($args); // prints 'ab'

This is similar to call_user_func_array. I think the method
newInstance() is what you are looking for.
