> Haskell is great, for what it's worth, but as with any language you have to reign in the AI's use of excessive verbosity. It will stack abstractions to the moon even for simple projects, and haskell's strengths for humans in this regard are weaknesses for AI - different weaknesses than other languages, but still, TANSTAAFL

I haven't had this problem with Opus 4.5+ and Haskell. In fact, I get the opposite problem and often wish it was more capable of using abstractions.

I guess it might be something with the subject matter and how I'm prompting. I prefer somewhat more imperative haskell though so that's probably a taste thing.
