what about memoizing the fitness function? call fitness on your
structs, and if it's memoized, it will return the cached value as long
as the struct is the same value. if it's changed, then it will
recompute. somebody correct me if this doesn't account for something,
but it sounds like the right a
This was posted about a little while ago, but a great deal more has
happened. Basically, Phil Hagelberg and I have been working on a nice
little date library for Clojure that doesn't rely on anything but the
Java date APIs. Last time I posted about this, a few people brought up
Joda time, which we
yes, that is why.

I say go for it. maybe swank could use it for macroexpansions and
stuff. the lack of pretty-print drives me crazy!

1) "use" and "require" differ in that use does what require does,
loads a library, but it also refers to the symbols in that lib in the
current namespace. So essentially if you want to use
clojure.contrib.def/defvar, if you (require 'clojure.contrib.def), you
would have to say (clojure.contrib.def

Under the suggestion of some people in the #clojure channel, I started
working on a date library for Clojure since the built-in Java one is
kind of a mess. It's not totally complete, but I think it could be
quite useful. It supports getting the current date and time, and
creating dates based on in

1 is actually an example of partial application of functions more than
it is currying. Haskell's currying makes partial application far more
natural though. In Clojure you can use the (partial ...) macro to do
this:
user=> (def f (partial + 1))
user=> (f 1)
2
2 is done using the (fn ...) special
my vote is for projecture or clojects

I am trying to write a macro to rewrite something like this:
(set-props my-jframe :title "blah" :visible true)
Into calls to the setter methods. I finally settled on this:
(defmacro set-props [obj & props]
(let [prop-map (apply hash-map props)]
