I think this is very important content that deserves to be expanded upon. Understanding functional programming is going to be more and more important as programmers face more and more concurrency in their programs (both locally due to cores and on servers
due to multiple users). Functional approaches can provide insulation from some of the problems that concurrency cause.
However, the pedagogical aspect needs to be improved upon. It was very challenging to complete the video, not because of the content, but because of pacing of the presentation... a pacing perhaps more suited to the written word.
This is the first of the tutorials to really get into the "meat" of Haskell and I enjoyed it quite a bit (especially the fact that I was able to write the solutions with only a few minor missteps in syntax). I may become a Haskell convert: writing type signatures
does make the code that follows much easier to construct.
