Also, identity works too:
#(identity "foo") ; equivalent to (fn [] "foo")

I've been thinking about this more. Suppose I do something like this.
(def my-ref (ref 1))
(defn f1 []
(dosync
(ref-set my-ref 10)))
(defn f2 []
(dosync
(ref-set my-ref 5)
(commute my-ref #(inc %
(let [t1 (Thread. f1)
t2 (Thread. f2)]
(.start t1)
(.start t2)
(.j
Hey all,
I couldn't find a good set of bindings that wrapped most of the BDB's
features so I wrote my own. This library covers most of its basic
feature, wrapping cursors, transactions, and key value functionality
in more idiomatic clojure.

Actually no, although that looks pretty fun.

The doc for commute says "At the commit point of the transaction, sets
the value of ref to be:
(apply fun most-recently-committed-value-of-ref args)".
Looking at the source code in LockingTransaction.java, that doesn't
seem to always be the case. I see this:
f.fn.applyTo(RT.cons(vals.get(ref), f.

I'm sorry for abusing the list for this announcement, but we are
lacking another information media at the moment.
We decided to unify the argument order for all functions, in that

#(quote "foo")
For this approach I would recommend `do`:

(let [x 5] #(do x))
Other than that I would recommend `constantly`
in this case, because it carries the intention,
while the #(do ..) look
There are two other ways to write
(fn [x] "foo")
1. Use quote
#(quote "foo")
2. Use the constantly function
(constantly "foo")
Both return a constant value.

Try either killing your Java process or changing the port you're binding on.

Guys,
I going through the peepcode tutorial, I am trying to run the code shown
below, but I keep getting :
*Address already in
use
[Thrown class java.net.BindException] *
I am using ubuntu, is there someway I can specify the bind address to fix
this problem.
Thanks

fn and #() are not interchangeable. In the first example, you simply

Hi all,
I am new to functional programming and thought this might be
interesting to others to see my approach to this kind a recursion
problem. I found this problem hard to think through, does anyone have
any suggestions for simpler solution to this type of problem?

Hi group,
This is an interesting discussion and perhaps not a bad one to dive

Currently (as I see it) all major decision making comes straight from

which features to implement/extend and if they go into core or not. It
would probably be
a good idea to move in the
