Over the years I have learned and dipped my toes in many programming languages, and I'd need some kind of reason to look into yet another language. What are Raku's main contributions to the programming language design space that I probably haven't seen elsewhere?

But as Perl-compatible regular expressions are available in many other languages, this is not really a reason for learning Perl itself, right? Or am I missing some deeper insight into regexes, because I don't know Perl?
That's true, but it's worth mentioning that using the regexes in perl is quick and even fun to write. They are built-in to the language. some people find it very convenient.
If you find yourself in a place with frequent one-off text wrangling or Unix admin problems some Perl knowledge is worthwhile.
This language looks cool! I also really like the page-by-page format for the tutorial, which strikes exactly the right balance (for me) between giving too little and too much info. As a side note, I noticed that the "Notes on using Unicode" page[1] referred to the quotation marks used in kanji-based languages[2] as "fancy." I think this kind of exotification of non-western cultures (where mundane things become exciti…
Thanks. I've updated that.

Learning Perl is worthwhile because it is ubiquitous on Unix-like systems and Perl-compatible regular expressions are the defacto standard regular expression syntax. Perl may not be as popular now as it was in the past, but it is still around and lots of legacy systems that were written in Perl are still in active use.

I find that regular expressions and text-wrangling tasks are faster and easier in Perl than in other programming languages due to its accessible syntax and regular expression engine speed.
This article shows the regular expression syntax in several popular programming languages: https://cs.lmu.edu/~ray/notes/regex/
This GitHub repo gives some regex performance test benchmarks: https://github.com/mariomka/regex-benchmark Perl is pretty fast among the scripting languages that were benchmarked.
If you are familiar with C / C++, then learning Perl is relatively fast and easy: https://perldoc.perl.org/perlintro
I'm so glad they renamed Perl 6, having it dangling for decades like a Sword of Damocles hurt Perl more than anything else could. At least both languages are now able to progress in their separated ways, and I must say Raku is a really pleasant language, and a joy to use.
I'm going to butcher my question so my apologies, I've heard Perl described as a sort of linguist / grammatical type of language, where you can solve the same problem using multiple approaches and syntax. Is this something Raku is drifting from or embracing? I think Raku is kind of interesting and I did try it out a few times whilst it was called Perl 6, but I'm not sure what its niche is. I mostly do Python for prof…
One that is particularly funky is the "whatever-star". This is a "" char that can be used in a few places to mean more or less... whatever. For example:
.map(-> $x { $x + 7 }) # result: (11 12 13 14)
.map(* + 7) # result: (11 12 13 14)
.map(* * 7) # result: (28 35 42 49)
I will note though that dwelling on these crazy/fun edge cases is amusing, but programs can look quite a bit more like a basic ruby app (with sigils) if you so desire.
I literally clicked on this thinking "Neat! Let's try something new" until I remembered it's just perl rebranded... unless i'm missing something?

As someone who wrote a limited amount of Perl 5 before writing a not insignificant amount of Perl 6 (now Raku), I find Raku syntax to be deeply Perlish while also being more modern and internally consistent than Perl 5. IMO Raku has three standout features: 1. Grammars in the stdlib [1] 2. The absolute most flexible multi-dispatch system of any programming language [2] 3. The best regex syntax of any programming lang…

If you insist on comparing it to Perl, you could consider it "Perl Re-Imagined". Just like "The Lord Of The Rings" is a re-imagination of "The Hobbit".

There are a TON of experiments and language mash-ups in Raku. Let's see here.... Types can include guard clauses that are evaluated at runtime. Typed multi-dispatch on top of that. In addition to normal "sets" it has "junctions", like some sort of funky quantum superposition or something. In theory those can be made parallel at some point. Stuff like that. One that is particularly funky is the "whatever-star". This i…
> (also yes, (* * *) will take two inputs and multiply them.)
That's true, but Raku also supports non-Unicode math operators, so the more idiomatic way to write that would be
(* × *)
