Yes.

What would the post-patch result be of that operation?

Hi :
Say, I have a (def *a (ref {:b [{:c 5}]})) .
I want to add 1 to the :c inside, how would I write?
(Note: the value 5 is in (:b 0 :c), while 0 is the array index)
(dosync (alter *a __ )) ; please help me fill the blank.
Someone mention I can use the zipper library or the walker
Hi,
I am a web developer and would like to write a small Desktop UI
application in Clojure for the popular Simplenote app.
http://simplenoteapp.com/
I was wondering what UI framework I should use. Anyone out there care
to suggest one that works best with Clojure?

Is this a weird idea?

Current results vary based on arg order:
(def xes (iterate #(str % "x") "x"))
=> #'user/xes
; infinite first ok
(= xes ["x" "xx"])
=> false
; finite first boom
(= ["x" "xx"] xes)
=> java.lang.OutOfMemoryError: Java heap space (NO_SOURCE_FILE:0)
It looks as if this particular case could be fixe

Hi,
here a "short-circuiting" (in sense of realising only needed values from
the passed seq) version of a "function and".
(defn fand
[s]
(let [s (seq s)
l nil]
(if s
(when-let [f (first s)]
(recur (next s) f))
l)))
clojureql.sql=> (fand (map = [:a :b :c] [:a :
OK, I should have just tried passing in 'and at the REPL before posting. Of
course, it works. Is this the idiomatic way? I'm still curious about
short-circuiting.

Hi,
This is a very basic question, but I can't find the answer anywhere. How do
you take the "and" or "or" of sequence? They are defined as macros and can't
be passed into "apply" or "reduce". Is there some reader macro character to
force it? Also, how does one write it so that it will shor
