This document is really targetted at people with some Java experience, and some functional experience, but people who would not consider themselves experts. In particular, it's not targetted at academics, or at least not at PL people. But hopefully it may contain some ideas that you find cool.
Part of the reason that I am posting this now rather than after I have completed a first draft is due to my relatively slow progress. I am hoping that if I post what I've got, you guys may give me some feedback and some cooler ideas, and that this enthusiasm will be enough to help me complete this in a reasonable amount of time. That being said, after this post I will not put up any more blog posts until I at least have an entire draft. If you want to wait until then to read, please be my guest.
So without futher ado, the current draft of, "How to Hack Java Like a Functional Programmer" will be posted at the following URL, and will be updated just as often as I work on it until it is complete:
