If you want to go from root to a normal user, that's easy. Just drop $EUID/$EGID to your real $UID/$GID (respecitivily):

use English; # For saner var names

# Do some stuff as root

$EUID = $UID;
$EGID = $GID;

# Now we're running as a normal user

Going up in privileges is harder. Probably the only realistic option is to execute the actual su (or maybe sudo) command and feed it the data to execute. (On GNU/Linux, you can pass in the data via the '-c' option to su, but this isn't portable).

I wanted to explore how Perl's closures can be manipulated, and ended up creating an object system by accident.
