For me it's not the paranthesis, but that Lisp posts always show low level code. At least half of my programming is tying together high level services and libraries. I know how I can express those concepts succinctly in Java, C++, JS, Swift etc. I'd love to see some examples of Lisp for something like a REST controller, where I call services, repositories etc.

I know how I can express those concepts succinctly in Java, C++, JS, Swift etc. I'd love to see some examples of Lisp for something like a REST controller, where I call services, repositories etc. You should look at Racket. Racket is a Scheme-like[0] Lisp that aims to be "batteries-included". It includes things like a web-server out-of-the-box. [0] it is technically a hybrid of R5RS and R6RS, so pedants can argue over whether it is really "a Scheme" or not.

  > whether it is really "a Scheme" or not It's not and it's not about being pedantic. Racket changed its name nearly a decade ago and, at that point, it already wasn't Scheme either. I have a post about where Racket (and Clojure) come from: https://klibert.pl/posts/clojure_and_racket_history.html https://klibert.pl/posts/clojure_and_racket_history.html

With more URLs you'd likely use something like this: http://docs.racket-lang.org/web-server/dispatch.html http://docs.racket-lang.org/web-server/dispatch.html for dispatch, instead of hand-coded function. It's notable for only using stdlib, no additional packages (beyond purely syntactic, Clojure-like, `~>` support). To be honest, the APIs exposed in the stdlib feel kind of awkward - like using SimpleHTTPServer in Python. Still, it's just a couple of lines and easy (automatic, in this example) in-process concurrency is not bad.

I have written an example web application for my cloud computing lecture. The code is not pretty nor 100% functionally and there are some bugs, but it shows how my applications work. It's just for demonstration purposes and therefore kept simple. https://github.com/dak0rn/Zwitscher https://github.com/dak0rn/Zwitscher Feel free to shout me questions or remarks.
