[tangentstorm]

I am such a person! I make J videos at http://youtube.com/@tangentstorm (many of them are recordings of live-coding on a single J application), work professionally in another array language called K, and also use forth (one of his other puzzle languages) for various things (currently working on a forth-like scripting language for an animation tool, for example).

I would definitely categorize J as having a strong puzzle culture. Many of the people who use it are just doing it for recreation and to stretch their brains, and insist on writing everything in "tacit" (J's version of point-free) style.

Personally, I'm more interested in building things. Most of my J and K code look like any other scripting language, but just very highly compressed.

I would agree that Haskell is not quite in the same category, and don't get the sense that Haskellers strongly favor a particular brand of bending over backwards to make things happen. But then again I'm not nearly as tuned in to the Haskell community, and he was writing this 14 years ago...
