I'm not real clear on what you *expect* to happen if this were to work
"correctly", but this is an amazingly bad idea, as it means that I, as a
random user from the Internet, can pass commands DIRECTLY to your Perl
interpreter to make it do whatever I like, by, for example, accessing
the URL on your server:

or something of that nature.

This used to be a rather common problem on Windows machines, when folks
would put perl.exe in their cgi directory, but I have not seen this done
on Unix systems before.
