map call and map constantly are actually inverse operations.

Hi Ángel.
I much afraid most of the information about Clojure is in English but for
some random blog posts.

really interested in participating in such a group.

I run SLIME with Clojure on Aquamacs, and I used Geoffrey Grosenbach's
emacs starter kit (http://github.com/topfunky/emacs-starter-kit) to
get set up.
The emacswiki suggests that loading the .emacs file is deprecated
(http://www.emacswiki.org/emacs/PreferencesInAquamacs), and I couldn't

Yes, a macro is required. Otherwise the symbols are evaluated.

Or, you could just write foo as

(let [vec-vec-of-str (vec (map (comp vec (partial map str)) vec-vec-

This let you write foo* to handle strings. Anyway, the key thing to

Hi,
Just chiming in a bit late -- just wanted to say that Clojure has

Hmmm... I'm torn. It certainly would be useful syntax, but it might
be confusing because of laziness.
I think the confusion is that it is designed around impure functions.
I think this would be better use dotimes in these situations.

That is indeed nice. Thanks for the code; I guess I don't really have
to settle for #(%) after all.
@RandyHudson: apply would work, but it's pretty slow, and not worth

Thanks Brian. In fact, I hadn't properly installed SLIME. However, I

It all seems to be working correctly now.

That works for functions with one argument list, but what about
functions with multiple argument lists?

Doc strings and metadata won't work either. It seems like I might as

Yes, you can make any symbol private. If you look at the definition of
defn- you'll see all it does is set
So you could do the same when defining a multimethod, just give the
name (symbol) of the method the metadata :private with the value
true:
(defmulti #{:private true} my-multi my-dispatch)
I'm having a bad day for typos, the example should of course be:
