I used Lincoln Stein's CGI.pm module (https://metacpan.org/pod/distribution/CGI/lib/CGI.pod#CGI.pm...) all the time back then. I wrote a Perl module for SMIL which I called SMIL.pm and emailed him to tell him and was thrilled when he responded. I'm strangely saddened to hear it has been removed from Perl.
It’s still available[1] (and maintained) for those that need it, but there are much better tools available for web work these days, like Mojolicious and Dancer.
