That's probably true. Reference counting is a good fit for tree-

Christofer,
This is a problem with the current version of Leiningen. There are a
couple of ways to work around the problem. Here is one:
Create a new Leiningen project.
lein new delete-me
cd delete-me
Open project.clj and change
:dependencies [[org.clojure/clojure "1.3.0"]]
to
:dependencies
Hi Tim,
Personally if you have done or would be interested in doing a quick vid
cast of how you progress through your workflow, I think that would be very
interesting.

An amusing thought but no thanks.

Fair enough :) - deal. Assuming I ever get to leave my pit of despair

Thank you, for stating this fact so precisely, thereby answering
my question.
I do have difficulties, though, to deduce this fact from the
reference manual.
But, well, there you go.

Hi Christofer,

I'm not so sure about this, but is it possible to throw an exception
when dividing by zero for example? I don't know if exceptions are the
right way of dealing with this at all, but at least this would be
bringing things more in line with Clojure.

Well, I also do not want to re-invent the wheel. Some of these
libraries are really optimized for both memory and speed (yes, I will
need both) and already provide a great deal of useful functionality
that I would otherwise have to implement myself. I just want to make
sure I am doing it right and

Hello David,

Here is one I wrote a while ago.

It's not "finished" (is open-source software ever really finished?), so I
don't know whether it will do what need it to.

I ended up just using ANTLR and it works pretty well from Clojure.
Most of my time was spent on the grammar and implementation, not the
ANTLR integration bits.

One way to think of it is that both assoc and assoc! create and return new
maps that are different than the originals they were given as input.
assoc never modifies the original map. assoc! might, or it might not. It
depends on implementation details. A correct Clojure program will never
rely o
Does the Clojure REPL provide a handle for getting the value returned by
the last executed statement? In Ruby's REPL, the underscore gives you the
last returned value. In Clojure, I'd love to do something like this:

Hi,
I've got two questions regarding meta information.
Question 1:
I can say
(def x1 (with-meta [] {:m 1}))
or
(def x2 ^{:m 1} [])
and will get my map back with either
(meta x1)
or
(meta x2).
But when I do
(def y1 (with-meta 'a {:m 1}))
(def y2 ^{:m 1} 'a)
only
(meta y1) spits the map back at m
Thanks, I didn't look at amotoen yet. Will do!
A library based on parser combinators would be ideal, something like parsec
in haskell. Although if in clojure world people usually take a different
approach, I'm open to trying it.

Yes, the REPL binds *1, *2, and *3 to the three most recent returned
values. *e is the most recent Exception.
