My thoughts after using Clojure for about a month

    The functional paradigm is a bit uncomfortable at first, but it does make problem solving feel... different. I personally find OOP to be the most intuitive for large scale systems design, but that's just me.

    Most models do not perform particularly well in Clojure, but OpenAI models fully utilize the power of the language. Subjectively, it kind of seems to match the personality. Data at https://gertlabs.com/rankings?provider=openai

      Thanks for the link!

      What would you say is missing from Clojure for large-scale OOP design? As I understand, Clojure gives you OOP a la carte. Objects (via maps/records/structs), polymorphic dispatch (via multimethods/protocols/case), types (via Malli/TypedClojure), inheritance (via derived, isa?, etc), some encapsulation (via defn-/^:private)...

      Not sure if I'm reading this right, but the "success rate" table for OpenAI models shows Clojure near the bottom. And if I switch provider to Anthropic, success rate for most languages, including Clojure, goes up dramatically.

    I wonder if the author is familiar with Smalltalk - it has a very small syntax. In some ways so does Lisp, in other ways it has more than every other language, depending on what you think about operators versus functions.

    I’m not quite sure what this means. How is it different/worse than all parens..?

    fyi I use paredit and just hit ) and it moves me past any kind of paren/bracket. But even without that you can just hit left and right..?

    > I am now generating this website with Clojure

    As everyone knows, you are not a true lisper until you have written your own static site generator.

    It gave me such a great high with how easy it was to add my own "templating engine" on top, implemented all using macros. The downside is that the crash came hard; there is so much more to a good static site generator such as optimizing the output, supporting scoped CSS, server-side rendering of SPA framework components, and of course integration with the Node ecosystem (for better or for worse there is just so much useful stuff). I have since moved over to Astro. It's still fascinating how far I was able to push my own SSG all by myself though.

      Heh, inspired by hiccup, I ended up implementing my favorite Clojure templating library but in Nix, exactly for the purpose of static site generation :) Even have a nifty demo of how it looks for that, it basically looks/works the same as hiccup: https://emsh.cat/niccup/examples/blog/

    With respect, this topic in particular has been beaten to death.

    I too liked Clojure when I tried it some years ago (agreed on the composition and data structures; both are _great_). But the real value-add is in the runtime, not the syntax. Java has a solid runtime but it's not yet as good as Erlang's, maybe even not up to the standards of Golang -- I am talking concurrency / parallelism here (for memory management I have no doubts Java is very good). And I know: green threads and stuff. Well, call me when you can do what Erlang / Golang can do. Then I'll look again, very seriously too.

    Programming language syntax scarcely matters. It does to some extent but we the programmers tend to over-romanticize it. The runtime and its properties are the much better thing to optimize for.

      When it comes to concurrency, what can golang's runtime do that is so special? When I tried it, it seemed like a worse version of Erlang's for people that prefer C style syntax. Depending upon your design space pervasive immutability is a huge boon too and golang doesn't have that but Clojure does - Erlang obviously having that and more.

      I always wished clojerl took off.

      • pdimitar 2 minutes ago
        I agree Golang is a worse version of OTP, no question about it, but if you are not allowed to code in Erlang/Elixir/Gleam (which sadly is 99.9% of the projects on the planet) then Golang is the next best thing.

        It has footguns, sure, but with library support and discipline it can get you very far.

        To me it's embarrassing that PLs still tout syntax and various other goodies, completely glossing over runtime. I might be missing something. But faux humble statements aside, I feel many others are the ones who miss something -- and that's the fact that doing stuff in parallel is a fact of life for 20+ years now and it's time all popular PL runtimes finally wake up to that fact.

        If not, I am simply not considering them. And I am not saying that arrogantly though it sounds that way; there are some PLs that I _really_ liked and was almost heart-broken that I had to abandon them and not work professionally with them. But I have enough experience to know that runtime choice matters, a lot.

        For the record, Racket was one of those PLs I abandoned. I know they started working on parallelism some years ago but I had to make a decision next week back then so, Elixir + Golang + Rust it is for me.

      Yeah, the content + feel felt like I'm reading this in 2013.

      Nothing wrong with that, it's a good thing that stuff is discovered anew [as opposed to being lost/forgotten], but it did bring a smile to me.

    > The seq abstraction, for example, means I usually don’t have to worry about what kind of sequence I’m dealing with

    Eh? That's completely lifted from CL (https://www.lispworks.com/documentation/HyperSpec/Body/t_seq...). Same for AREF/NTH, there's ELT.

    Other than that, I agree, CL is baroque yet needs some hole filling here and there.

    > Lisp: everything is a list

    But that's wrong. Not even a little. Unless you mean LISP 1.5...

    > Too much syntax

    Funnily, I'm mostly okay with the new vector/set/hash-table literals, my big problem and that of some other people is the use of vectors in macros/special operators instead of lists. `(let [a b] ...)` instead of `(let (a b) ...)` is _not_ okay.

      I haven’t used clojure in quite a while but what’s the issue with (let [a b] …)?

      Is (let (a b) …) even valid clojure?
