I am writing a game in Clojure, and I often need some functions to return
whether they succeeded in doing what they are supposed to do (for example,
moving that unit one field to the left may fail due to... I don't know, a
wall?).
But if there is one thing I really like about LISPs is the idea
Alright.
1) Why I need success state: this is a turn-based game, and I want to
advance the world clock if and only if the player makes a valid move.
2) identical? makes sense. I generated some unnecessarily large data
structure and checked, it really is ridiculously fast. Thanks!
3) Returning ni
(defmacro dbg [x]
`(let [x# ~x]
(println (str *file* ":") "[" '~x "=>" x# "]")
x#))
I personally use this macro. It shows only the file name (I can't find
out how to get the current line number).
This one has the advantage of still returning the same value as the
expression itself.

Hello,
I just read some of the clojure.core source, and when reading map and
range, I noticed that inside lazy-seq, recursion doesn't seem to stack
overflow. I then tried it myself on some trivial examples, and indeed,
I can take hundreds of thousands of entries from such a list without
anything h
(defmacro dbg [x]
`(let [x# ~x]
(println (str *file* ":") "[" '~x "=>" x# "]")
x#))
Without the line number, because I don't know how to retrieve (neither
could I find anything on it).

Hey,
I got myself a copy of The Joy of Clojure.
It's a fascinating read, thanks for the recommendation!

Hello.
I'm currently hacking away at a small project (turn-based game) that
as of now spans over 7 namespaces/files.
I'm working in an emacs/lein/swank environment.
lein run works without problems.
lein compile/jar/uberjar fails, yelling NullPointerException at
game.clj:1.
