I did not spot examples of this in your diffs, but I assume you mean to prohibit conditionals like:

    if ($a || $b and $c || $d)

As I understand it, perl introduced low precedence operators precisely to allow this.  Why disallow it?

I don't understand the prejudice against commas used this way.  What is wrong with:

    $i++, $j++ if defined $k;

rather than:

    if (defined $k)
    {
        $i++;
        $j++;
    }
