I've just uploaded a video walking through some of the source code for Pandoc. I plan to create more videos like it (on Pandoc and other open source/free software projects), and I'd appreciate your feedback. https://www.youtube.com/watch? v=FEFETKhhq8w&feature=youtube_gdata_play er I think Haskell is particularly well-suited for this type of study: - The code tends to be concise, and parts can usually be analyzed in isolation thanks to explicit state. - Even after 10 years of exposure to Haskell I feel like I still have much to learn about idiomatic style from the writings of others. - I've run across the same misconceptions about Haskell in the professional world (and had some myself in the beginning), and would like more people to see what Haskell really is like outside of papers and blog posts. Please let me know if there are other projects you'd like to see me cover. Thanks.
