How about using the Taint module on CPAN. It offers a tainted() function that should do what you want. And can you beat the price?

-sam

UPDATE: I mean the Taint by Dan Sugalski. If you just ask CPAN.pm to install Taint you'll get one by Tom Phoenix which fails tests on 5.6.1 and, even worse, isn't free software! It's restricted to being used only for "TESTING AND DEVELOPMENT PURPOSES" whatever that means. Yeesh.

Even worse, the Taint I meant is baked too. The archive unpacks to all lowercase files. And fixing that, it fails to build under 5.6.1.

I give up.
