FWIW I have never touched ELPA but got a setup with SLIME from CVS
plus SBCL and Clojure. A rudimentary description can be found at
[link]
The only part that feels tricky is compiling swank for which I needed
a Maven setup, IIRC.

Hi,

Sounds reasonable.
I don't know whether it's in contrib already but I'd very much
appreciate a few macros lifting the burden of Java's io-lib with
Reader, BufferedReader, File, PushbackReader, WhateverReader
and ...Writers. Coming from the Lisp world this feels rather ugly to

I doubt the memoize functions provided therein will be directly useful to you, but you may find a few lines of helpful code there. Best of luck with your experiment.

I am very much in favour of a clojure.io library. It's difficult to do
much useful computing without I/O, and what there is in clojure.core
is insufficient.
Your selection covers all I need and more, so it's fine with me. My
only suggestion is to move all I/O-related functions from clojure.core

Reference-counting GC's in most LISPs are pretty much a thing of the
past. Between needing to do cycle detection and having to lock the
reference counters in concurrent environments, they just lose to many
ways. Generational garbage collectors were big last time I

Yes, this is working variant

Indeed -- that works nicely. I tried going back to a completely non-ELPA-ized setup, but it was too painful; the trick was installing technomancy's github repo of slime *in addition* to the ELPA packages, which all depend on each other.

Something else to look at might be the Apache Jackrabbit project at
[link].
I've been looking at tools along these lines as well, and recently
looked at Redis for the same reasons. Right now, though, I'm focusing
my attention on Jackrabbit which is an implementation of the JSR170

Yes. I think it is of much interest. What if I stored a shared data
structure in redis (only because its the fastest), using your memoize
variant, and process (maybe even updated it) it in parallel from
different Clojure nodes. Some kind of primitive map/reduce mechanism I
think.

I've been looking over our use of contrib in our large-ish project
at work. About 90% of the invocations of contrib functions are
I/O-related. I wonder if it would be a good idea to include a clojure.io
namespace in Clojure itself. I've mentioned the idea a few times on IRC,
and people seemed to be very much in favour.

Hi,
do you use a rather recent checkout of SLIME? If so, you may want to
read the thread [link]
Can't say whether that's related to your problem, though.
Cheers,

Thanks, Rob. I followed your instructions after not being able to get
Clojure to cooperate with my normal Swank/SLIME installation, and it
works, but only to a point: The SLIME REPL buffer (invoked via the
function `slime-repl') falls out of step with the *inferior-lisp*
buffer.
This never happens to me when using SLIME with a Common Lisp, such as

I'm trying to think of scenarios where circular references would be a
problem in Clojure. When does memory actually have to be allocated?
Inside a let block, most often. When lexically scoped variables are
passed to a function, their reference count increases as they are
bound to its parameters, but they're also immutable. One thing about
