I did, and it works like a charm. Couldn't figure out how to hint an
array of objects (what should I put instead of the old #^objects?
I still get it to work in 300 ms (which is not great but something I
can live with).
Thanks for the replies,

Thanks for sharing this. Coincidentally, I just wrote my first Clojure
program which was... an implementation of Conway's Game of Life :-) I took a
different approach - I represented the board as a vector of vectors of
integers (1 for alive, 0 for dead) and then implemented a new-board function

BTW, I still haven't been able to figure out how to write this

Ok, I found the leak. I guess I'd call
I'm writing some fairly complex code involving lazy sequences. I
appear to be getting a space leak from what looks like something that
is still holding a reference to the head of the sequence.

There was a discussion on
I would appreciate, in a similar vein, an amplification of the "Use

My web application needs updates from time to time.
When this happens I often have to stop the server and
shut down the JVM. Then the old (current) directories can
be replaced by the new ones, and I restart the server.
It's okay when there are several copies of the server
running behind a load bal
Thank you, that was the problem.
I wonder if Stuart should change this line:
(defn clojure-source? [file] (.endsWith (.toString file) ".clj" ))
to this:
(defn clojure-source? [file] (and (.isFile file) (.endsWith (.toString
file) ".clj" )))
just to make sure directories like "myproj.clj" don't
