Hello
What is the idiomatic way to implement the classic collide-with
function in Clojure?
I would like to implement something similar to the following (pseudo
code ahead):
(defmulti collide-with foo)
(defmethod collide-with ["asteroid" "spaceship"] (print "Boom"))
(defmethod collide-with ["aster

clojure-contrib also has a str-join function, which could be helpful
for joining SQL conditions:
(use '[clojure.contrib.str-utils :only (str-join)])
(str-join " AND " (map identity [1 2 3]))

Every time I stick a println into some Clojure code to debug it, I
think to myself, "This is Lisp! I should be able to insert a repl
here!"
The problem is of course that Clojure's eval function doesn't know
about the surrounding lexical scope. So I started asking myself, what

Dispatch on the class (or interface) is sometimes the "trick"

Yes, just to make sure not waste Rich's time. I did doubt and triple

Looking at the stacktrace it looks like this is because of swank_fuzzy.clj.
I can start up the SLIME Repl no problem, I see your exact same stack trace
only if I try to trigger fuzzy completion via C-c TAB.

It turns out the doc string for filter was dropped during a checkin
earlier this year. I surprised no one noticed sooner (I guess everyone
just knows how filter works).
I have filed ticket 219 with a patch and hopefully we'll get it into
1.1.
I didn't see any others missing, have you seen others?
I like that too. I'll have to think about how we'd do that.

I didn't know the costume hierarchy at all, it seems to be very

I understand it is coupled to the Java object hierarchy.
