If you want +++ operator, rather use them for addition with lower precedence, for example this 

$a + $b ** $c + $d ++ $e + $f ** $g + $h *** 
        $i + $j ** $k + $l ++ $m + $n ** $o + $p

would become 
(($a + $b) * ($c + $d) + ($e + $f) * ($g + $h)) * 
        (($i + $j) * ($k + $l) + ($m + $n) * ($o + $p))
