As a Haskell novice I really appreciate the effort to put this together and look forward to seeing more of them. The video is high production quality and the pacing was fast enough that I didn't get too bored, even though I already had a pretty good understanding of the Haskell that was covered.

Hey all, The connection between difference lists and accumulators is probably well known, but I only recently realized it myself and a quick Google search didn't find turn up any page where this was explicitly stated, so I thought this observation might be useful to some. Every beginner Haskell

surprisingly, deepseq is not used as much as I thought. http://packdeps.haskellers.com/reverse/deepseq lists a lot of packages, but (after grepping through some of the code) most just define NFData instances and/or use it in tests, but rarely in the „real“ code. For some reason I expected it
