you can learn clojure without learning lisp first :)

i solved a few little thingy with clojure now, including some euler
problems, java interop and an asteroids clone.
my summary would be:
* very nice to write +1. i used clojure's collections for a lot of things,
and they made a good impression
* you need to plan far ahead compared to java. in java,
exactly which part of OOP is missing in clojure that you would like to use?
if you took my java code and ported it to clojure, the main difference
would be (a b) instead of b.a , but the main design would be similar

it happens with both clojure 1.5.1 and 1.4.0. when intellij tries to
compile clojure files, something strange happens. if i remove the option to
compile the files (and instead just use clojure.main and run them) there is
no problem

i am not interested in details or single features, i just want to know if
there is some magic editor out there that i should look into because it is

imagine a simple problem: you have a collection of numbers and you have

hi,
i'm half done with my asteroids clone. i stumbled over a few problems
and wanted to know how others already solved them :)
i am used to "less concrete programming". i ask my tools to do the
actual analysis and coding for me:

here's a part of my clojureoids-code:

contact #()
full-test (fn [element] (and (type-pred element) (bounds-check
element) (contact element)))]
(filter full-test (:game-elements @world-at

hi there,
i stumbled over two odd things
1) -> and ->> have the same source code. why is that?
2) why can't i use "(-> "hi" #(println %))" directly? why do i have to
put my function into a symbol first? is there a way to avoid this?

i went a step further:
since my asteroids are all immutable, they don't contain a renderer.
the renderer would either require a reference to the asteroids data,
position, size and so on - if that "changes" the renderer would be
obsolete - or would req

no need for "IRender" since everything has a java.awt.polygon. i just
draw it. in a sense, the polygon is my IRender and it's data is the
implementation.
