The real question is whether a programming language that has lost traction, mindshare, and focus ever gained it back? It's probably no coincidence that Python's rise was at the same time of Perl's stagnation.
Almost overnight everything about Perl seemed very old fashioned. Maybe their style of programming will suddenly become popular again? But doesn't look like it's coming soon.
Unlike Java/C#, I would say github is a good indicator for Ruby.
Scheme -> Racket Common Lisp -> Clojure ML -> Haskell
If perl followed this format and did a rebrand that is essentially the same thing, they would be more likely to pick up traction. Perl just in the name itself gives me a certain connotation. Typically the older variants of languages for the most part die off, while the newly branded ones gain traction, but carrying on the same basic mission. This last one is particularly sad to me personally the Standard ML ecosystem is still to this day incredibly robust and production-tier, and yet it is very much a dead language.
