Karl, Do you happen to have laying around anywhere a copy of the original perlDL article? The Perl Journal stopped publication ~10 years ago and Dr. Dobb's Journal website has been hosting the articles. However the Dr. Dobb's Journal website ceased updates at the end of 2014. So it might be nice to have a copy of the original article that we could host ourselves, before it is lost forever. It still exists here http://www.drdobbs.com/pdl-the-perl-data-language/184410442 but who knows for how long?
