Yes, that's the kind of semantics I want, but it would be rather

Hello,
I've posted an example of a simple model-view-controller GUI skeleton
in Clojure here:

The GUI has a text box and a panel which draws what you type. It's not

Hi,
This `lazy-seq` over a `when` and `cons` idiom seems fairly common. Is

Since clojure-slim is not bundled in the distributed ZIP for 1.0.0, I'm
going the build all three libraries from SVN tag "1.0" (r1365).
I've figured
take, drop, take-while and drop-while, exactly mirror the definitions
in the Haskell Prelude, FWIW (except for the non-camel-case names)
This order makes sense if you're into currying:

(0 1 2)

Thanks for your replies.
I've always thought of "for" as a generator. Basically just a loop
that produces a lazy collection. So it actually seems very natural to
me.
But anyway, I think I shall just write my own generator function using
lazy-seq and be done with it then.

I'm trying to accomplish the following:
Create a lazy sequence of calls to f() while pred() is true.
And an elegant way to do this seems to be:

This can be worked around with:

Hi Bruce,
It looks like your namespace only implements an interface, rather than
extending a class. You need an ":extends..." line in your (:gen-

As stated in the subject, the clojure-contrib build process doesn't
compile all namespaces.
Some of them of course must not be compiled (like macro-apply, due to
its evilness), but as far as I can tell, some were simply missing from
the build file.

One question, though: I see that you want to name the artifact
"clojure-lang" and not just "clojure".
Why not just "clojure" as is the case for the ant build script ?

I would bundle clojure-slim.jar as a "classified" clojure, like Maven
calls it. So the final filename would be "clojure-lang-1.0.0-slim.jar".
To use this one instead of clojure-lang-1.0.0.jar, the following
dependency needs to be declared:
