This whole Python/Perl competition was always a bit silly. Both languages had and have their place. I would say Python is so much more popular because it found a niche in ML because of how much more easy it is in Python to interface fast C modules. So you get to write simple Python programs leveraging blazingly fast math libraries. That was always a bit more tricky to do in Perl.
But Python as a language is definitely not as flexible as Perl 5. Last time I checked Python didn’t even support multi-line lambdas because its inventor hates those. Python is very much designed in a top-down approach and tries to guide all Python programmers into how there are supposed to solve their problems. Perl 5 was designed with its famous „easy things should be easy, hard problems possible to solve” philosophy. It allows for meta-programming in all the right places which a seasoned Perl developer can reach to when necessary. Perl 5 is a nice middle way between C and Lisp.
That being said modern JavaScript turned into a powerful language that fits well into both the frontend and backend side of a web application nowadays and, hence, kind of replaced Perl as glue language for the web. It will also push Python out of web backends at some point I believe.
Raku / Perl 6 has been the R&D project it set out to be with interesting new features and smoothed out syntax.
You can use either freely as meets your needs. If there's a "debacle" here it's the misunderstanding.
Perl 6 was meant as the bravest experiment with C-like syntax in 30(?) years - attempt to nicely mix few programming paradigms and styles. And that we really have in Raku.
They was talking "Perl is dead" but it never was and isn't. Maybe it looked as clinically death with out of body experience into ideal language heavens but since decade or so it is back. Solid and backward compatible as always.
And there was problem for some with "parallel language versions" marketing so Perl 6 was renamed to Raku. The harder question was "Which one I need to learn ?", but it is newbie programmer question, you need to know many languages because it is standard programmer life experience. And it is XXI century and many technologies are around.
On the other hand Python usage is scientifically researched as being a "write abandonware" language :)
Sorry, but originally it was meant as the replacement (and I was physically present at its announcement at OSCON in 2000). It wasn't until 2008 when the "sister language meme" was generally accepted, that the paths diverged instead of being sequential.
Ok, multi-lang virtual machines wanted to replace Perl5 binary.
But: :)
- multi-lang vm's are proof that v5 syntax wasn't mean to be eradicate at all cost
- there was no plan or push to instantly obsolote, uninstall and deny of Perl 5 usage
- I'm sure there was a conviction that some Perl 5 installations will stay for long time period into the future. Or as long as possible ~~ forever.
So it wasn't like Python 2.7 replacement. And plans even assumed continuation. And some from the start wanted to have both langs :)
To counter that, Inline::Perl5 (https://raku.land/cpan:NINE/Inline::Perl5) was developed. It gives you access to 99.9% of Perl's functionality transparently, such as being able to subclass Perl classes in Raku, and vice-versa.
