Did some major projects for my employer using Perl (coupled with Java of all things) in the 90s. Then I learnt Ruby and put aside childish things (jk). I then dropped Ruby for Elixir and Python for the sort of projects that I would have used Perl for, back in the day. As a semi-retired sort, I now keep my Elixir and Python skills up-to-date and can't remember the last time I even tried to read any Perl. I know it's still there, doing work, but then so is COBOL.
What I miss from then are the O'Reilly books about Perl. Peak O'Reilly. Every one a joy to read and packed full of goodness. Without being 1,000 pages long. Oh, and CPAN.
Perl 6 was only ever a distraction - I was already out of love with Perl by then and Ruby (and obviously Rails) came along at the right time for the next project.
