That's cool. I remember when threads was quite literally the perl scripts translated into php. I bet Rick doesn't even remember anything about perl anymore.
My Perl knowledge is shot. I still have to do some from time to time, but it takes me forever to do even simple things now even though early version of threads were written in Perl
When I converted threads from Perl to Php I actually wrote a Perl script to do 90% of the work for me in translating Perl syntax to Php
