Re: my newbie question...
Oops. Sorry, I'm clearly too tired to post. Thsoe examples aren't quite right. Those are the threading macros. (-> one two three) expands to (three (two one)) -> and ->> do the same things, except -> threads through the first argument of the functions, and ->> threads through the second argument.

my newbie question...
So i've used this because I picked it up from numerous tutorials but I've never really understood it, can I get a some decent background information on ->> and ->? I picked them up from compojure tutorials and don't feel anywhere near comfortable enough w/ what is actually going on.
