My understanding of commute is that it would not restart the transaction, it
would just apply the function. So I wrote this little test program:

I noticed that some multi-word functions separate the words with a
hyphen while others don't. For example, butlast and drop-last. Surely
changing names of core functions now would break lots of code, but I
wonder if it would still be worthwhile in the long run to do this
before 1.0 is released.

i was confused by the meaning of coll, too . . .even at a more basic level
of not knowing that it meant collection. I even thought at first I was
seeing "col1" or that the second lower('L') was a capitol(i). I read it as,
"column one" in my head.
Is it accurate to call it "some-seq" or something?

I would say "thread" is used here colloquially - i.e. "works the expr
through the forms" and "form" is as defined in clojure.org/reader.

I recently wrote on my blog that using #' was a good way to make sure
that you get the function definition you want despite the symbol being
rebound within a let. For instance:
(let [list 10]
(#'list 1 2 3))
=> (1 2 3)

Anyone have a better method to go from a symbol to a namespace
qualified symbol? I'm using this ugly kludge now:
(symbol (.substring (.toString (resolve sym)) 2))
I'm keeping a map of currently traced functions and the key is the

More as a note to future Clojure doc'ers than anything else: It seems
that noobies (including myself) get bitten by the lazy versus
immediate evaluation functions all the time (e.g. for versus doseq/
doall). If this problem isn't solved through naming conventions

that we are very concerned about combatting the criticism that lisp has too
many parens?

i was talking about something related in the chat group, but I'm not good
enough yet to implement it. I want to rewrite the doc method slightly in a
way that would go a LONG way for newbies. The current way actually looks
like java . . . like the parens are around the input params. But that's

Hi Rich, hi all,
A question: is it possible to kill or interrupt an agent during a long-

(def the-agent (agent nil))
(send-off the-agent really-long-action)
;; Oops, I changed my mind.
(interrupt the-agent)
;; The thread running really-long-action stops,

For the past few weeks, I've been having problems with my Internet

The selections function in combinatorics returns more than what I
need. (selections [ 1 2 3 4 5] 3) will return both (1 2 3) and (3 2

several times to write a function to filter out the 'duplicates', but

I'm not sure exactly what you want to remove, but it sounds like you
might be looking for something like:
(set (map sort (selections [1 2 3 4 5] 3)))
or:
(for [i (range 1 6) j (range i 6) k (range j 6)] [i j k])

if you want to generate the values lazily rather than all at once.
