Has anyone written a replace-subtree for zippers?
I need to replace an entire subtree with another one (from another
zipped structure) and found out that zip/replace won't help me there.
Writing my own has proven remarkably difficult, or perhaps I'm missing
something obvious.
Any help appreciate

Dear list,
I am writing some functions to serialize and deserialize clojure data
structures,
but somehow they do not work and I am stuck.
The functions are as follows:

(defn ser

load-string evaluates the contents of the string, which brings in all
of the compilation machinery, which produces bytecode, classes, etc.
Classfiles have a 64K size limit in typical JVM implementations.

Thanks for all the helpful suggestions guys. I put together a little
article on determining coin flipping probability with Clojure. I'm
still a newb, but this Google Group is helping me progress with the
language.

Seems like opinion is pretty evenly divided here. I'll leave the
library as-is for now, give it some time to see how things play out.
In the mean time, as a compromise, I've added str-utils2/partial,
which is like clojure.core/partial for functions that take their
primary argument first.

I use defonce and defonce- quite a lot.
I'm all for inclusion of c.c.def in core.

Hi folks.
I am starting to make what will eventually, with some luck, become a
freely available, nice, pretty and easy-to-use GNU/Emacs cheat sheet.
Right now, it lives in a mind-map, has some commands I use frequently
and needs input badly from more experienced Emacs users.
I would appreciate a

Dates are now final for the Copenhagen and Aarhus Clojure meetings.
Trifork and Azul Systems are sponsoring the events: Trifork provides a
room, some drinks and sandwiches, and Azul is letting us run Clojure
on one of their large boxes (864 cores, loads of RAM ;-). I will be

It would obviate defunbound

In common lisp I can do this:
src-> (defmacro macro-hello () `"hello")
(eval '(macro-hello))
no problem.
In clojure:
(defmacro macro-hello [] `"hello")
(eval '(macro-hello))
gives me an error. Have I done something wrong? After further
investigation I found that a pre-defined macro/function
