I'm eager to see Clojure turn 1.0 because it is a fantastic language

is time to put the message out there that clj has made the journey

Well, perhaps if str-utils becomes the universal standard for string

Hi Meikel,
I did that already and it did not help. I also explictly unset my
CLASSPATH env in the shell from which I start ant (just to be sure)
and checked that the "clojure.jar" property in clojure-contrib's
build.xml is correct.
I do not see this behavior when I switch clojure to svn rev 1339.
I tried to use an anonymous function in map but it didn't work.
user=> (map #(%) '(1 2 3))

but with a normal anonymous function it works as expected:
user=> (map (fn [x] x) '(1 2 3))

Thanks

I think my misconception was not the missing identiy fun but rather that the
first element in the list is the function
that is evaluated.
so #(%) is trying to evaluate whatever % evaluates to, e.g. (1) and therefore
there is the

Why this fixing on one somehow blessed function? When the

You can use java's pack200 tool to compress your jar down quite a bit:

I was having trouble building clojure-contrib after having updated
both clojure and clojure-contrib. Clojure was already at HEAD.
I have a habit of running "ant clean" before compiling.

which was complaining about "get-method".

I finally got around to buying your book yesterday. The thing that

But Rich has written that - it's from Rich's forward to Stuart's book.

Wow, that works great. Thanks a lot for your help Laurent.
Can you think of any reason why mapcat isn't lazy by default though?
I'm wondering if this is by design, or simply because we haven't had
the time to update all the library functions to be fully lazy yet.
