Add Perl 6 to Wikipedia's multi-paradigm programming languages list

[Tyil]

Wikipedia has a Comparison of multi-paradigm programming languages, which currently lacks a Perl 6. This should be rectified, but to do it properly I'll need to know which paradigms are supported and know which pages (preferably from the docs itself) to cite.

[AlexDaniel]

What would be the best page to document this? https://docs.perl6.org/language/faq?

[AlexDaniel]

Or a new page linked from https://docs.perl6.org/language.html?

[JJ]

Pretty much all of them. I'll check it out.

[JJ]

Let's try and add a reference here. Some of the things are not so easy.

• [x] Concurrent using channels.
• [x] Constraints through where and but keywords.
• [x] Dataflow Feed operator
• [ ] Declarative
• [x] Distributed using the Cro module
• [x] Functional
• [x] Metaprogramming
• [x] Generic via parametrized Roles
• [x] Imperative
• [ ] Logic
• [x] Reflection through the Mu object and methods such as .perl, .gist. (AlexDaniel: maybe actually through MOP?)
• [x] OO
• [x] Pipelines (AlexDaniel: maybe yes because everything gives a Seq? Also there are feed operators: ==>)
• [ ] Visual
• [ ] Rule-based
• [ ] Other paradigms

[JJ]

I'm going at this from the bottom. Rule-based is not, visual is not. Pipelines... This is the document for C++. Seems to me it's something like the Feed operator?

[JJ]

I would say that's pretty much it.

[JJ]

Anyone else wanting to help here? Should I assign it to myself?

[AlexDaniel]

Feel free to.

[JJ]

Done. https://en.wikipedia.org/wiki/Comparison_of_multi-paradigm_programming_languages#Language_overview Thanks everyone!

[AlexDaniel]

• [x] If it is referencing Cro module, then it should be marked as “Library” (according to other entries in the table). That said, I don't understand that column altogether. It should be a No I think…
• [x] There's a column called other, and for Julia it mentions “Multiple dispatch”. Seems like something similar should be appropriate for Perl 6 also (also what about “reactive” and “native shaped arrays”?)

[AlexDaniel]

But generally it's good I think!

[AlexDaniel]

“Lazy lists”? :)

[AlexDaniel]

Grammars, Junctions, Gradual Typing… none of these are paradigms, but why do others list “Array (multi-dimensional)” and “optionally lazy”?

[JJ]

You are absolutely right. Thanks for the feedback. I'll try to change that, but that will be tomorrow :-)

[AlexDaniel]

To be completely honest, I think that the whole page should be nominated for deletion. Looking deeper at the content, it's very low-quality, cluttered and unsourced. Also, the page is completely useless because everyone is trying to stretch the definition of “paradigm”. But if we're adding perl 6, I think we should be very strict about our own contributions.

[JJ]

Whoa, whoa, whoa! Having suffered deletionist librarians in the Spanish Wikipedia, I don't wish the deletion of even a single iota of knowledge in the Wikipedia. It's got its merit, but you are right about "stretching the definition of paradigm"... I would rather go for deleting that column, but anyway I would discuss it on the discussion page. It will enrich everyone involved.

[JJ]

OK, addressed @AlexDaniel 's concerns. And fixed Go row while I was at it, which had a format problem. Closing at 1, closing at 2, closed :-)

I couldn't find the "where" and "but" keywords, but type constraints are not constraint-based programming ( https://en.wikipedia.org/wiki/Constraint_programming ). I've linked a library instead.

When I was a student, there was a Distributed Computing research group in the computer science department. Their operating system didn't run on a single computer, it ran across multiple computers. It was effectively an operating system for clusters, as opposed to an operating system for a single computer. A key part of their setup was that if a node was heavily loaded, it could bundle up a whole process, ship it to a different node, and it would just continue running there as though nothing had happened.

Having said that, that was a distributed operating system, not a distributed programming paradigm. But I'm not sure there is a distributed programming paradigm (as opposed to distributed computing, which is a thing).

HTH,
