I think the question still deserves a proper answer.

This is indeed not at all about his code. I don't care what he thinks of vaccines and COVID - I just as much don't care what Linus Torvalds thinks about these things. They are damn programmers. Their business is to ship reliable, usable, secure software.

I got permanently banned from the Raku community rather silently. What happened, what is the common history, and honestly, what is the path forward for those who stay.

This post is mostly meant to reach out to the community itself from this exiled state - therefore generic Raku banter isn't very welcome, and neither are further invalidation attempts from the people personally involved in my ban: they have had plenty of representation and there is no reason to assume we can have a meaningful discourse.

It's a bit ironic that now we went down the static rabbit hole so much that we don't realize it's more the opposite: by adding more to your language and compiler to enforce static checks, you turn the compiler itself more and more into a runtime that you are just going to run ahead of time, according to a potentially vastly different set of rules compared to your real runtime. There is no reason why you couldn't do something like this by will but it's just not worth it after a certain point clearly.

I wonder where you got that impression from. For me as well, it's rather the overboard lecturing response that seemed like an invocation of "Trevors axiom".

By the way, what even defines "simply a blog post"? That's just a media format that doesn't say much about the content itself, does it? I do agree with the sentiment that it would have been good to know what the article is even going to be. Not even the paragraphs were very helpful in this regard. It does improve the reception of an article if it meets the intended audience.

In retrospect, this article is mostly about a basic compiler frontend language and how to bootstrap that into a fully-featured concatenative programming language. Which to me personally is a "hm, okay, interesting" kind of thing but I didn't read the article for this premise. I read it for the "new antisyntax language" and feel it was clickbaitish.

Some diversity doesn't hurt, though. On my keyboard, it's actually easier to type than the backslash for starters.

Maybe a fast way but is it a fair or even helpful way, if you recognize that it "quickly became a bad name for the project"?

So following your logic, "some of the worst" includes the vast majority of actually used languages and tools. Must be cool to be on the special side. :)

Taking a look at the bigger picture, it does indeed seem like the Perl philosophy lost to the Python philosophy overall.

Looking at the hip n cool languages, not just Python for scripting but surely Go and to some extent Rust as well for native stuff (Dart for scripting also but it didn't outright "win"), these are mostly languages that deliberately simplified things. Yes, even Rust - it needs to be compared to C++ and its biggest feature is basically that it doesn't let you do all the things C++ does, within a very similar model.

The only language that I heard is going against these trends (but I'm largely clueless what it's actually like) is Julia which sort of has its own "lay" niche like Perl did back in the day, and is mostly winning based on the premise that it's a performant scientific language.

The industry obsesses over costs of adoption, stability, maintenance; in short: how to get the most out of the least actual new development. It does make quite a lot of sense, to be honest, although sometimes it's really demotivating at an individual level.

And frankly, "learn the language, duh" usually comes up when the language is complex or unintuitive for no practical purpose. Of course there will be people who always complain if they have to learn anything but I don't think they make the majority, or even a significant minority, in the software engineering world. "Learning the language" is only as much of a virtue as the language itself serves its purpose, which includes easy of use and the readability of someone else's code.

The problem isn't whether the conclusions you draw are favorable or not, it's that they are not legitimate. It's getting tiresome that I have to repeat it: I'm not at all arguing either in favor of Perl, or against the "write-only" narrative that imo applies to other languages as well, including C++, Scala, Common Lisp, Ruby and whatnot, and I quite clearly know what it means when somebody says Raku is a "write-only" language. Newsflash: it's not about visual appeals, it's about mental portability across people.

> You do realize, I hope, that saying stuff like this doesn't really make the "write-only language" cavil that's dogged Perl throughout its history seem any less fair...

Surprising, right? I frankly cannot parse that sentence but yes, by now I really hope it's clear that I'm not arguing with the "write-only" narrative. I'm arguing that there is a world of things where software doesn't have to be about sticking to the same monolithic code base for decades and pass it around across dozens of people. That there is a world where it is indeed more important to write code than to read it.

> And once again I am saying you have failed as yet to convince me those possibilities might offer productive benefit, especially when I have yet to see the theoretical advantage of language flexibility in microservices materialize in practice.

I hope I suceeded in convincing you about factual things about signatures, reflection and the existence of accumulation. I don't have research studies about the productivity of various programming languages in a microservice-based architecture; if you have something like that, I will be happy to read it.

> Instead you seem to plead language flexibility in microservices more or less as an excuse, on the idea that niche languages for which knowledgeable engineers are rare as hen's teeth face no barrier here because, after all, you can always throw the code away and write more. And that is not convincing

This is not convincing because it's a strawman. Let's throw the "niche language" part away and let's replace "after all, you can always throw the code away and write more" (which is true but indeed no argument) with "a small, single-purpose, well-tested tool of any sort is best replaced when that single purpose wears out". Which is what I stated. And it makes sense, given that it was designed and tested around one single purpose. Maintenance is not a virtue but a common technical necessity. If you don't know when to let go of software, then ironically enough, you might as well have been exposed to too much Perl.

Anyway, considering the topics you did not respond to, one can deduce what points I did nail. Also, it seems we are getting away from the insult motive, that way it may be more useful for somebody who just reads.

> The apparent variance between list syntax accepted by the reader and emitted by the printer

Could you provide an actual example for this? I suspect this is a simple misunderstanding.

> 'o' for function composition? Square brackets to reduce over an operator? Square brackets with a backslash to map?

I never used 'o' myself but YES, square brackets to reduce over an operator. Indeed, I see nothing wrong with that (okay, I actually do but not with the principle, rather the parsing). And "square brackets with a backslash" is NOT a map, it's a produce. The blog post got it right.

> function signatures as first-class values (...what?)

Okay, now give me a break... this... is a "what"? Are you real now? A perfectly sensible and useful feature, a "what"? To be able to investigate function signatures and pass them around appropriately without constant hacking, is that bizarre? I guess airplanes are also bizarre to some...

So yes, I think what you present here might be the other extreme: rendering anything that might be slightly clever as "weird" or "complicated", even if it clearly reduces the custom tinkering each individual developer would have to do...

The situation is a bit touchy because I think your characterization of the Perl mindset living on in Raku as well (C++ is a similar language in a way) is legitimate but it seems to be based on "fortunate" prejudices and stereotypes rather than a good understanding of the situation. You haven't seen the bad parts yet and you apparently called some of the good parts bad. Not sure if it can be helped. I don't think the language will be cleared up anyway but I also wouldn't want to go as "unclever" as you seem to find desirable. Languages like Python and Rust can thrive despite not being completely dumb. Opinionated yes, dumb no.

Also, I have been thinking that maybe the way to find industrial use for Raku (or this broader mindset overall) is to outright reject this framing that all projects need to be monolithic. Yes, you may be right that Raku will never be a language where dozens of people work on millions of lines of code together, for decades. What if your services can be broken down into pieces that CAN be managed by a couple of people tightly co-operating? What if these services can be developed and deployed so efficiently that instead of maintaining them for eternity, you can just start anew and replace them cheaply?

There is the common wisdom "what one person can't fully comprehend, definitely contains flaws". There is some truth to it for sure, and it does seem like with the rise of microservices, there would be place for software developed in a much more distributed manner. Now, there are practical reasons why Raku didn't catch up, at least not yet - but they are absolutely not language philosophy reasons.

It would be invaluable feedback if you could point out what you find so bizarre? I mean, the "let's define some ad-hoc postcircumfix operator" is a weird flex for sure but otherwise? I could only see basic non-magic subroutine definitions and appropriately used operators.

I don't know, this is "second-hand intel" for me, pretty sure I read it in a very old article from someone of the likes of Carl Mäsak, Moritz Lenz or another early-day Rakudo contributor...
