I won't, because it would probably be quicker for you to run the one-liner several times (it's already parametized) than it would be for me to rewrite it to do multiple values at once. And it won't really stay a one-liner afterwards :)

But if you insist, I can tell you how I'd do it!

First, instead of ($var, $val) = @ARGV, which maps one pair only, I'd use an associative array to slurp in multiple pairs:

%updates = @ARGV;

Now, instead of $var I need to iterate over the values of %updates, and instead of $val I need to say $updates{whatever-the-curent-var-name-is}.

Probably this has taken me enough time already, so please assemble the parts yourself :)
