I've also been using my own version of a map-to-values function
extensively and it would be really nice to have something like that,
either in contrib or in core. It comes in handy surprisingly often.

Because that's all that declare does:

Docstrings seem designed for fairly terse comments about the nature of

Just a quick thought (and before I've had my coffee no less!), but I
think what I'd do is replace the boolean *end-search* with a
*search-state* var that could be either :idle, :running or :stopping.
Then in search-stops, just set *search-state* to :stopping -- you
don't need to actually wait for t

I am trying to set up an env that would be hosted on my dropbox or usb stick

Problem is that it works at home, but at work lein deps is unable to fetch

Solved.
The problem was maven proxy settings.
After adding settings.xml file to home works like a charm. I am answering

You should require clojure.contrib.monad and bot use it.
(ns my-namespace
(:require (clojure.contrib.monad :as m))
m/m-bind, for example.
Then you can define your own m-bind without conflict with an existing one.

I don't think marshaling closures will ever happen without changes to
Clojure itself. I haven't looked into how much work it would require,
or how much it would impact Clojure'

Monads are mostly used because they are necessary in Haskell. In
Clojure the urgent need is not there. However, you can sure get some
cleaner and/or more composable code if you use monads in your
advantage.

Hi,
I'd recommend looking at how plt-scheme solved this problem (see [1]).
They actually defined alternative readers in which either prose or code

I'm having trouble writing code in one namespace that instantiates a type
that is defined in another namespace.
I have two source files:
other.clj defines a function called my-fn and a type called huss:
(ns my-project.other)
(defrecord huss [x y z])
(defn my-fn []
(println "my-fn"))
core.
Types created by deftype & defrecord are Java classes and you'd have
to use :import to bring them into another namespace:
(ns ...
(:import my-project.other.huss))
Or if you have multiple types,
(:import [foo.bar Wibble Wobble])
It might be simpler to define a factory function and use that (th

Hi Michał,
Thanks for the explanation. I hadn't made the connection between the fact
that defrecord creates a "proper" java type and the fact that a Java class

Hm, I would guess that the self-call gets "hard-wired", since if you

(defn fib [n]
