I'm trying to create a macro called "procedure" so that:

expands to

I'm stuck because I can't figure out a way to generate a symbol
outside. I'm a newbie at macros, so I don't know if there's a better
way around this:

Hi Rock,
Clojure isn't designed as an array processing language, so it doesn't have
multidimensional array-slicing or matrix algebra tools built in. That's just
not what Clojure's trying to be, and you're right, immutable data structures
might get in the way. There's probably nothing stopping you

I like to try and keep my level of nesting under control, and this
often involves hiding or re-structuring the let macro. The for macro
can implicitly assemble a let macro for you, but with a limitation
that the :let clause can't be first:

If the Java layers are not already thread safe, you are facing a real
problem if you just try to layout some Clojure code on top of them...
You would have to be careful about isolating chunks that are thread safe
then look at what's left.
The difficulty then would be to find a way to introduce Clo
Hello,
I was trying to download a zip file using clojure.contrib.http.agent and
writing it to a file using clojure.contrib.duck-streams.
Apparently the zip file is getting corrupt because I was trying to treat
the stream as a string.
Is there any way to use duck-streams to write data as binary?
What if I wanted to use Clojure for scientific computing, and in
particular for doing linear algebra and matrix computations a la
MATLAB?
What would my options be for representing matrices, not to mention,
especially, MULTIDIMENSIONAL ARRAYS?
Would java arrays be the way to go, or nested vectors
I think the point of this style of api is you just define your functions like
(defn one [] )
(defn two [] )
and call the function like
(redis/with-server *db*
(one) (two))

Hi!
I am currently investigating if it is possible to convert a part of a
big Java system to Clojure. The reason for this is to make this part
run in parallel and hence ease the implementation by porting it to
Clojure. The problem is that these parts of the system is today
setting and changing a l
