Maybe setting the EUID (Effective User Id) is enough for your purposes: check $> documentation in perlvar.

Update: Though, note that you can do that only when the code running with the EUID changed is controlled by you and safe. Otherwise, it could be made to change the EUID again in order to execute arbitrary code as root.
