Saw this in a scala mailing list thread:

Should the clojure hash be fixed?

I use a modified version of tools.trace (or rather the old version
called clojure.contrib.trace, but works with 1.3), you might be
interested in some of the additions (sorry not well doc'd at the
moment):

in the trace will be t

Is there any attempt to make distributed transactions?
The usage scenario is the same like in JEE apps.
I mean, there is a web service call, the transaction is started, there
are some changes to db, some jms sends and when there is no failure
all is commited.
Maybe someone is already using glassfis
maybe avout is what you're looking for?

Fixing the underlying map / hash tools would be awesome, of course,

Well, I can't speak for Michael, but we want them because we need to
update the database *and* send events notifying other parts of the
distributed system about the change. We really don't want to do only
one *or* the other, because that requires that we get into the fun
world where distributed to

Yeah, I hadn't thought of the issue of the refs, but I don't think
it's a exceptionally hard problem to solve. What we are discussing is
basically the same thing that mutable languages deal with every day.

I know I can bind *out* to another stream like *err*, but is that the only
way built-in to Clojure?
(binding [*out* *err*] (println "This will go to *err*, not *out*"))
If it is the only way, is there some library perhaps where someone has
implemented a function that lets you specify the output s
Immutant is going to have distributed (XA) transactions.

Like this?

String hashing uses the default java hashCode method which contains the
vulnerability.
user=> (= (hash "Ey") (hash "FZ"))
true
user=> (apply = (map hash ["EyEy" "FZEy" "EyFZ" "FZFZ"]))
true

I am trying to learn how to use core.logic. Here is a toy problem

Yep. I should have mentioned that I know it isn't difficult to write one,
but in something I'm writing up I wanted to avoid reinventing an
already-existing wheel if it was already in a well-used library.

"Furiously" is probably not the right word, but XA is definitely on
the roadmap. It's just a matter of wiring up the TransactionManager
