I’m sure someone will be like “um akchuly” to my explanation. But for me it’s good enough to think if it that way.

I’ve worked in Haskell and F# for a decade, and added some of the original code to the Unison compiler, so I’m at least passingly familiar with the subject. Enough that I’ve had to explain it to new hires a bunch of times to get them to to speed. I find it easier to learn something when I’m given a practical use for it and how it solves that problem.
