Description:
------------
i don't know if this is a bug or not, but it seems that php doesn't allow for $class::method(arg), this might be done using call_user_func but, it's simply annoying

Reproduce code:
---------------
<?php
class test
{
    final static function testing()
    {
        echo 'hello';
    }
}
$class = 'test';
$class::testing();
?>

Expected result:
----------------
hello

Actual result:
--------------
unexpected T_PAAMAYIM_NEKUDOTAYIM or something like that :D
