It got me to thinking how "easy" it would be to write a perl virus, obfuscate and encrypt it, and call it in a wrapped up system or exec. Post it in the OBfuscated code section and see who bites. Now I KNOW there are plenty of SAINTS around here, but something COULD slip through.
Now I, of course, would never do such a thing, but someone could. If you aren't sure of excatly what a program does, DO NOT EXECUTE it! It could delete c:, / , or any number of evil things.
