I have no idea how many of you both care at all about JavaFX and are
planning to go to the JavaOne conference tomorrow Monday in San
Francisco, but there's apparently going to be a talk about using the
JavaFX platform from alternative languages, particularly Clojure, at 4
PM. I myself can't go,
that function call in the macro does prevent
the error. I don't understand it.

Functions can now have metadata. This is great, and very useful for

I'd like to request that now the (fn name …) form pass on any metadata

be proxying AFn instead?

I would love if this happened; it could probably be implemented in a
backwardly compatible way, since you're currently not supposed to use

Yes, http://github.com/joshua-choi/fnparse/tree/develop. You must use
the latest tree in the develop branch (which is at the time of this
writing commit baf3b39f51fdd3893471f52d330336b5a794fa6d).
Thanks for the help, and I look forward to what you figure out.

Actually, disregard the message above! You don't want the latest tree
on the develop branch; it currently throws errors because defalias

When it comes to naming factory functions—functions that create things—
clojure.core gives four precedents:

2. Name it a shortened version of #1. vec.
3. Prefix #1 with make-. make-hierarchy, make-array.
4. Prefix #1 with

As a small note, according to http://clojure.org/reader, Clojure

characters, *, +, !, -, _, and ?. Spaces aren’t allowed, but the
keyword function allows them anyway because it doesn’t do any checking

I see why you want to create your own reader macros—you want to set

Sorry for asking this here, but it's about the Clojure IRC room, which
is kind of related to Clojure, being this group's sister help
resource.
I know nothing about IRC, but I've been using the Colloquy application
for Mac OS X to connect to the Clojure IRC room on irc.freenode.net.
It was working
Thanks for the link; it's helpful. I've registered with Freenode as
joshua-choi with a password and nickname, and my IRC client informs me
when I reconnect that the server has identified me as joshua-choi.
However, when I try to send a message, I still get the same error.
Could anything else
Ah! Never mind! I just got an email telling me that I had to verify
the account! I did that, and I can now send messages to the room (I
think). Thanks a lot!

On creating an infinite range, I think it'd be wonderful if Double/
POSITIVE_INFINITY or something like it would be bound to a core
symbol, such as infinity or something. That'd way, one would be able
to do things like (range 3 infinity) or ( infinity 5).

Come to think of it, this would also work for me: keeping the vector
of pairs, and instead using filter to get the values of a key:
(defn get-from-pairs [pairs key-to-fetch]
(map #(get % 1) (filter #(= key-to-fetch (get % 0)) pairs)))
(I wish the key and val functions were defined on vectors
Is the function of the filter identity call to make (map
isInteresting pixels) a lazy sequence? I thought that the sequences
map returned were already lazy, but I could be mistaken.

Oh, I didn't know that. It makes me wonder, then, why integers were

Ah, well. I guess since let can't be changed, it's then a choice
between using accessors or being more elegant. Thanks for the reply.

I'd love for that to happen—either error-kit support in test-is or
test-is support in error-kit. clojure.contrib libraries should be able
to use each other with no worries, since they'll be installed together
just about always.
