Reports of perl's death are greatly exaggerated.
Also, please try Perl 6. The marketing may be a cautionary example, but the language itself reflects 15 years of polish.
While I respect that Perl development is still going, I haven’t seen it used by anyone in production for at least 15 years.
You should have skipped cPanel though from that list. That doesn’t build credibility ;)
I think by that they meant "where I've actually seen" (e.g. c ompanies parent worked, visited, friends have etc), not that in general one can't get 10 or 1000 examples of businesses still using Perl from the whole of the internet.
It would also likely be better (more readable and maintainable) and faster written in something else (did a partial Python port to understand what kind of munging the script actually did, the Python version was 50% faster, and a bit shorter though the latter may have been because I didn't test/check all features and some of the edge cases may have been missing in the non-default options).
