I'm looking for a way of mapping a uid (unique number representing a system user) to a user name using Perl.

Please don't suggest greping /etc/passwd :)

Edit

As a clarification, I wasn't looking for a solution that involved reading /etc/passwd explicitly. I realize that under the hood any solution would end up doing this, but I was searching for a library function to do it for me.
