I've only had a couple of minutes to work with it, but I'm already
liking it. I just can't keep switching between Emacs and IDEA and
IDEA is the work that pays the bills!

Hello Ilya,
Thanks for the workaround.
Crud. I suspect this is something weird with the way that the GitHib
gem server works. I'll try to repeat the problem on Ubuntu as soon as
I get back to my computer. In the meantime, you could try these
commands:
sudo gem uninstall djspiewak-buildr
sudo gem install djspiewak-buildr
Hi,
After having used Clojure for a few months now, I'm still having lots
of trouble separating my mutable code from my immutable code. My use-
case is pretty typical I think, so I'm wondering what sort of
structure everyone else is using.
Here's my current structure.
I have an engine that

I agree regarding concatenation as well, but I think the case for
comparison of non-numerics is still pretty strong.
Are you referring to using , , =, with objects that implement
java.lang.Comparable?
i.e. given x.compareTo(y) == -1
( x y)
= true
I'm not sure of the details since I don't know much about Java, but that
sounds about right. I'm working on a date library, and having to use
functions like earlier? and later? rather than , , =, and = feels
awkward.
You are probably thinking of dates as numerical longs rather than
actual

Seriously, what's with this API? I give up.
Yeah, I spent an hour or so sifting through nio before throwing up my
hands :) Also, (getBytes (slurp file)) sounded like it would work, but
it does charset encoding.

You want Apache Commons IO:http://commons.apache.org/io/
If most of the state is in the sprites and they don't co-ordinate then could
you make the sprites agents and use watchers to manage their forward
notifications.
Any global state (the event loop) can be managed functionally by recursively
passing the updated state as a parameter into the event

I have been trying in vain to get the namespace docstring of anything
with print-namespace-doc. It doesn't say what exactly it wants as an

ns-name, which wants a symbol, so I give it a symbol. But the symbol
