Slowly wrestling myself through getting to know emacs.
Ok. autoload works fine. Didn't realize I have to open emacs with
a .clj file for the clojure-mode to load. Now looking where this
'Cannot open load file:slime-repl' is coming from.

I'd personally write that as:

There is also when-let, which can be used to iterate over sequences:

Hi everyone
first of all, this is my first post, so if I ask FAQs or deserve to

kind you do to learn ;) ), I got a working convesti

Since you say you're an Eclipse user, one answer could be : use clojuredev
(eclipse plugin supporting clojure development),
and wait patiently for this feature to be included :-).
More seriously : clojuredev, while still a baby compared to slime, has some
interesting features worth considering fo
I wanted to say compared to emacs+slime+clojure-swank, of course.
There are also netbeans and jetbrain Ideas implementations, also.
I just posted here because you told about eclipse, but those other
environments are good, too !

Good. This one concerned me, as I'd like to use pmap given its simplicity,
but that would prevent other from calling my code in their own pmap (and how
would they know not to do that).

I agree with what Laurent said about clojuredev, I've been having

Ahead of Time compilation might be what you are looking for . This lets you
distribute.class files rather than your .clj source files, and makes for
slightly faster code at startup.

That's correct; this will not load the code. It just sets it up so that
the file gets loaded on-demand when you open a clojure file. I will add

Sorry, I didn't mean to suggest that you held that opinion.
In any case, I am still learning Clojure, so I think I should restrict
myself to newbie questions until I am better at it. I hope I will have time
to implement an open-world reasoner, which would help make the discussion

Hi Jeffrey,
There's not a straightforward answer, since there so many
implementations of Cells floating around now.
The original implementation, written by Ken Tilton for Common Lisp,
*does* handle circular dependencies. It is single-threaded and
synchronous. It uses a global time counter to m
See neman.cells:

I believe there is at least one more implementation somewhere.

This inspired me to write a general purpose version:
(defmacro let->
"Provide a name that will be bound to the result of the first form.
For each additional form, the variable will be
used in the invocation, and then rebound to the result of the form."
[varname start & forms]

You could use cond:

Nice, I would definitely use this!
One comment/question: would it be more efficient to expand to a bunch
of nested "let" statements, rather than nested function calls? I'm
not sure how Clojure handles "let" under the hood, or how Hotspot
inlining works here. Here's my version:

I like that implementation. The recursive call makes it much cleaner.
A slight improvement (?) yet:

A conversation on IRC tonight[1] got me thinking... Although most
collections can be safely printed, such as at the REPL, this is not
true of all collections. Probably the best-known exception in Clojure
are infinite lazy sequences, where printing can cause an infinite
loop:
(prn (iterate inc 0
