I enjoy programming in conduits but somehow never come across a big enough problem to really make use of them. They encapsulate a whole class of problems in a very comprehensible and modular way. The higher order conduits like `scanlC` and friends also enable more complicated ideas than just the usual `map` and `reduce` variants you usually see. It's quite straightforward to model all sorts of chat-/websocket-/trading-bots as conduits for example, I wrote a blog post about it at https://wjwh.eu/posts/2022-05-06-haskell-conduit-bots.html.

Btw @rkrzr I hope you don't mind me asking but "niet geschoten is altijd mis": are you looking for freelance assistance at the moment at all? I've been consistently impressed by the engineering work done at Channable, for example the Aho-Corasick work and the stuff relating to compact regions, but am not able to commit to fulltime work at the moment. Lately I've been mostly working with Ruby and DBA/db performance stuff, but Haskell is the first language I got properly good at and it will always have a warm place in my heart. I'm pretty experienced at the intersection between backend dev and DBA/devops type problems and if you are experiencing any problems in that area I would love to help out there. Looking at the channable github page, I just realized I even made made some PRs for Icepeak way back in 2020. :)

You don't need to use them in "big enough problems". I've used them with great success in a microservice architecture: had to consume some events, do some processing and spit out some data into Kafka. Absolute straightforward code, I could just focus on the "processing" part and ignore the boring plumbing. I'm sure that a lot of apps fit this pattern really well: consume data, processing, spit new data.
Thanks for the kind words @WJW, we are pretty proud of our engineering culture as well :)

We are unfortunately not looking for freelance assistance at the moment, but we regularly have Haskell Engineering positions open, so perhaps that will be interesting to you in the future.

That's too bad but understandable in this economy. I did notice the open position on the careers page, but long term employment does not suit my situation at the moment. Best of luck and keep me in mind if the situation changes! :)
