Ask HN: Best Haskell projects and gists to learn from
Can someone recommend a list of well documented, well-written projects and gists that are written in idiomatic Haskell?
Projects/gists from beginner to advanced level are appreciated, just mention whether or not the code you are recommending is beginner, intermediate or advanced level code.
Beyond that, who's Github profile contains some of the best Haskell code out there to study from?
