Not really, but monad can be a bit tricky at first.
Your first email was a namespace related problem, that has little to
do with monads.
But it can be better to start with other part of clojure and come back
to monads later.
They can be useful to refactor code or write a nicer program, but you

I think Lisp is very well
That's probably due to a problem with clojure.core/munge I recently
reported on the Dev list [1] -- see a proposed patch attached to my
first e-mail in that thread. I notice there still hasn't been any

Yes.
Have someone (for example your editor), do your indentation for you.
By typing on tab on a good editor, you would have has:

[ (prefix->postfix arg1) (prefix->postfix arg2) op]))

Never looked closely at count definition.
I assumed it was a forawrd to .count of Counted, which explains my problem.
I kind of remembered the O(1) of Counted and get mixed up.

Ring stores session data in an atom. Reloading re-defines the atom to
be empty. Sandbar uses Ring's session store. I have made a small
change to Ring in my branch which fixes this problem. See

How are you going to handle session? How are you going to handle

I mean, I can counter by just create a hello.html in apache

Your point has been made, simple things are simple. When you need to
print "hello world" you don't need to bring Clojure into the picture.
You could have given a much simpler example of needing to print "hello

All of these things are *possible*
I suspect $ is in munge because Rich and company may want to use it as
a special reader character. $'s used to access inner classes work
fine. I'd be fine with that as long as there's still a way to access

I'm using thrift-generated Java objects heavily inside hadoop and it
would be nice to access object properties using keyword notation
instead of .getPropertyX. At platform speed of course.
Searching the list shows someone else interested in the same thing but
no answer.

People frequently complain about Clojure's stack traces, and there are
now some enhancements in the master branch. In particular, there is a
new function in clojure.repl, pst, which prints a nicer stack trace of
the most recent (or a supplied) exception. It also has depth control.
pst is automatica

I assume I'm just clueless here, but the last commit I see at
http://github.com/richhickey/clojure is one from Stuart Halloway in
June. Where do I find this so I can try it out? Or, what version do I
have to tell leiningen I depend on - 1.2.0-snapshot, 1.3.0-snapshot,
or something like that?

Hi,
According to drop-while doc, (pred item) will return nil. It struck me
as I thought the form would only return a boolean. Is the doc correct?
What would be an example?
user=> (doc drop-while)

clojure.core/drop-while
([pred coll])
Returns a lazy sequence of the item

Yes, it's in the ZIP file, distributed through http://clojure.org/downloads
It's in the ZIP file at target/clojure-contrib-1.2.0.jar
You can also download it directly at

Can you clarify? Maven-aware build tools (e.g. Leiningen) should not
be trying to downlaod the "clojure-contrib:complete" JAR file.
Instead, referencing the "complete" project as a dependency should
transitively give you all its dependencies. Does that not work?

Boolean seems to work:
user=> (drop-while #(< % 4) (range 10))
(4 5 6 7 8 9)
