Huh, that is artful. Looks like I need to get my dev environment in
shape so I can keep up with the changes!

My previous post got lost in a black hole somewhere... so lets type a

Yeppee !
That's a perfect match with my schedule for the next 6 months.
We will launch our new projects under 1.2 and port the existing code to
it in the following weeks.

Did you try unquote splicing? i.e.
(defmacro deriv-fn [fn-args exp v degree]
`(fn ~fn-args ~@(deriv exp v degree)))
Also, posting a link your exact macros would help :)

No, not yet. However this problem is known and it is being worked on.
For now you have to resort to cl
I'm not sure how simple this is. If you want the code to be able to take any
English sentence as input, parse it, and reword them as question.
It's far more work than a simple email can convey. :)
You can probably start with the clj-opennlp as the first step
to parse the input.

Um, the "Clojure 1.1.0-alpha-SNAPSHOT" version reported by Clojure in
the above and the "svn/tags/1.0" version of Clojure that you mention
lead me to ask:
Where do you get your clojure.jar / Clojure sources from?
These days you're supposed to use one of the following, depending on
your stability
I've spent most of the afternoon trying to get swank-clojure to work
for me. I tried ELPA. I tried Lein. I tried directly pulling in the
git repositories.
No matter what I try, I get the following:
java.lang.Exception: Unable to resolve symbol: with-bindings in
this context (basic.clj:469
I need to write a program that will rephrase an English statement into
a question as many different ways as possible.
Which libraries will be good for creating a simple version of that?
Examples will be nice too.
Thanks a lot.

When I here refs of refs, it's a code smell. Granted, sometimes they

1. Is a tree really the right way to represent your data? Perhaps you

In ClojureQL I do not see how to join three or more tables using the

Hi Nicolas,
First to answer, but not necessarily the most accurate answer you'll
get. Be warned ! :-)
You can nest refs into refs. But in that case, don't mismatch the ref
and a particular value of the ref in your mental model.
You will be reminded of this in your code because you'll have to der
Dear all,
I have a problem where a lot of concurrency could be gained by having
a tree of references.
ie a tree where each nodes contain a ref to a set of similar tree.
(I know that having mutable trees is asking for troubles, but that is
quite necessary for the things I wish to do.)

Thank you very much for the quick answer. That makes a lot of sense.
If there were no return value, there would be a need to throw
exception on subsequent reads. You're right, that would add a lot of
complexity.
I wanted that because I have a bunch of set updates (insertions) in a
transaction and

When it's all said & done, I'd say 1 to 3 months.
Patches are flying around like crazy right now, and they're mostly
related to getting the last bits & pieces in order before an RC. Rich
has mentioned that there's going to a bit longer RC period this time
around, this is to accommodate
