I've heard a lot that Google App Engine's use of many JVMs makes
Clojure refs, etc. less useful than they are on one JVM. I'm curious—
what are the consequences of using a ref normally in Google App
Engine? How would it be broken? Would each JVM, invisibly, each store
a different value for the ref
Should be fixed in the latest commit.
Any of the following will work.

(import '(System.Windows.Media Matrix))

Hey, you're one up on IronRuby, which had a bug where one couldn't create an

I have no doubt spy is easy to use and fairly straightforward to
encapsulate. But doesn't this strategy somewhat complicates the use
and deployment from Clojure? I would think a user would prefer a
"pure" Clojure solution that hides the Java hooks and does not depend
on third part jars.

I've personally found using the spymemcached through java introp extremely easy,

etc.

Why doesn't Mono have a BigDecimal analogue? It shouldn't, in principle, be
difficult to create an open-source-friendly implementation backed by GMP.

Hi,
I am just learning Clojure (and Lisp) and I was thinking about
developing a Clojure memcached client as an exercise. I am in doubt
about the best way to do it. I could just write a thin wrapper around
some existing Java memcached library (like Dustin Sallings'
spymemcached or Greg Whalin's me
Hi.
Thanks all, for your comments.
> You need to use a bigger number than 1000 for these results to be meaningful.
Out of curiousity, why is this?
Does the JIT do something different after 1000 iterations?
Or is the concern simply that the variance of the mean estimate is too
high with 1000 vs.
Well, after removing all jars except clojure and clojure-contrib, I
still get the exact same error. Apparently, it doesn't like the import
statement in java_utils.clj in clojure-contrib. Very weird.
I think I'll revert back to clojure 1.0 for now, and try again at a
later date.

FWIW, I've run both on my Toshiba dual core laptop with ubuntu, and
they return approximately the same values.
(and there is some JIT trickery going on, as I got:

Hello Rich,
It's been a long time since I've not hijacked a thread, so let's get back to
this bad habit exceptionally :)
While the example provided by jon may not be the best ones, as you pointed
out below, I feel there still is a problem: dynamic scopes and threads.

Short answer: It's a bug.
Longer answer: It's a problem with type propagation in let. It'll
take me a day or so to fix it.
The handling of non-primitive value types by the compiler still has
some problems. Any place where the JVM compiler is discriminating
between primitive types and reference
