I think you have to decide what you are aiming for. Is this a "solution" or
another tool in the toolkit. I think Rich noted a while back that Clojure
can access many distribution technologies. So if you want a solution right
now you can wrap one of those up and off you go.

Cool!
One of the things I really like about Cells is that it can really take

Thanks, Tim, glad you like it. I agree one of the most interesting
uses for Cells is GUI programming. I'd love to see a library for
building Swing GUIs this way, although I would want to keep the GUI
functions separate from the cell library itself.

There is something I don't understand about Clojure. There are
multimethods (great), but I can't seem to find objects they can operate
on. I come to Clojure from a Common Lisp background, having done a fair
bit of CLOS programming. Mind you, I am not necessarily a fan of overly

I have been reading through the API examples on:

Why is that the goal? I mean, the JVM provides a well defined, high

Mmm, I could create a third namespace that contained the common
functionality. But it is an artificial separation. If a user read
through the source code, he would think "why is this code separated
into two files, when it's dealing with the same thing?"
Anyway, here's my use-case:
I wrote a sprit
user=> (take 0 (lazy-cat [(println 10)] [(println 20)]))
10
nil
What you see here is not an issue with lazy-cat, but rather an issue
with take. The current implementation of take evaluates one more than
the n passed to it.
So in this case, 1 element of the seq is evaluated and "10" is printed.
I think this behavior is as-intended, although I agree that it is
confusing.
The reason for this stems from the fact that lazy-cat returns a seq,
and the only allowed representation for the empty seq is "nil" (i.e.,
Java null). Thus, lazy-cat must always do enough evaluation to know
whether to r

Hi Kevin,
You should try clj-doc:

user> (let [s (HashSet.)] (.add s "test") (contains? s "test"))

Doing something like Datalog would be terrific fun. I might
contribute if there is interest.
I'm not an academic, so most of my contributions would be on a
practical level. We'd need someone else to provide the deeper aspects
of theory.

Mark,
Glad to see you are putting some more work into clj-doc again. I tried
compiling it a couple weeks ago, and after I downloaded the 4 or 5
libraries it depended on and fixed some of the references to code that
had been moved, I got an exception when I tried running it. I gave up
after that.
