Learn how easy it is to sync an existing GitHub or Google Code repo to a SourceForge project! See Demo
I've added a link to your project from my links page. I try to link to as many libraries and articles as I find -- since we all have different backgrounds and perspectives, and since most of us are better coders than writers, I think that it's in all of our interests to expose the users to as many different viewpoints WRT documentation as possible. I expect that there will be a number of folks for whom your library makes more sense based on common background, just as I expect a number of folks whose exposure stems more from the C++ STL side who would gravitate more toward jga.
I also added this blog entry briefly describing your library.

You'll probably be interested in these two, also, as I expect the issues will give you have problems making FunctionalJ generic.
oops - misarranged one of the links, and sourceforge won't let me edit
