Functional Programming Made Easier

Quick announcement: I will be going through Charles Scalfani's (from what I've seen so far) excellent book, Functional Programming Made Easier. It's almost 2000 pages long, so there's a lot to take in. The length is mostly owed to the fact that it's a comprehensive guide and the code examples are repeated on change so you don't have to jump back and forth while going trough an iterative exercise.

I have (almost) finished the first part, and am posting about it publicly here so I am accountable not to give up halfway. Naturally, I'm coding along, and it's available here.
