Ladies and Gentlemen,
I present for your viewing pleasure the Clojure Cookbook (beta :) ):

Gregg Williams has set up a framework at Getting Clojure to gather material,
primarily focused on newbies, on how to flatten the learning curve.

I found that even without patching, most functions in
clojure.contrib.math already correctly handle big nums in 1.3:
Handles big nums in 1.3?
absYes
ceil Yes
exact-integer-sqrt No
expt No
floor Yes
gcdYes

I generally use the ns macro to jump around my namespaces (like I use
ls to change directories in the shell) , and use a convenience
function I wrote called ns-nuke, which gets rid of all functions
defined in that ns. Then I use reload, another convenience function,
which just uses that namespace

Hi,
did you already try out paredit [1]? That mode is absolutely fabulous
for programming any lisp and provides much more than just closing
parens.
Give it a shot!

I'm curious what you don't like about the automatic insertion scheme
that you talked about. I'm using Parenedit with emacs and I'm quite
happy with it. I think the scheme is quite simple... whenever you type
'(', it inserts ')'. Similarly with '[' and '{'.

Hi,
Writing Clojure code tends to require a larger mix of "()",
"[]" and "{}" characters than other LISPs I use. This
sometimes makes it a bit tiring to write those balanced
expressions.
Writing balanced expressions has been addressed in editors
mainly by providing the automated insertion of matc

While updating the benchmark programs I wrote for the shootout web
site for 1.3 alpha1, I came across a program that required much more
memory to complete in 1.3 than it did in 1.2. I boiled it down to a
simpler program that has similar properties.

And I didn't say it was a macro. It's a macro character tied to a reader
macro, and it participates in read-time macroexpansion.

How are other people handling the process of reducing code in their

Possibly related -- I've noticed that lein repl on Mac / Linux seems
to break type hinting.

That's a false distinction. You used `quote' rather than
`list'. Macroexpand your form to see:

A while back I wrote a Base64 encoder, and have been using it to play
with the primitive enhancements in 1.3. After a bit of fiddling I was
able to get it from around an order of magnitude slower than apache
commons-codec down to about 5x slower.
