Hi all,
I was wondering if there was an idiomatic functional way to accomplish
the following:
We have some parameters, and we want to build a collection based on
those parameters. The collection could have as many as n items, and
whether and what items get added for each of the n possibilities

iiuc, erlang doesn't have transactions so it is a different situation.
when you redefine a function, the next time the (standard approach to
writing erlang actors) tail call goes back into the function it will
be actually going into

Ok, I have a new one.
Reader errors don't tell you the name of the file that had problems:
eof.clj:
(defn foo [a]
(println "hello")
$ java -cp clojure.jar clojure.lang.Repl eof.clj
java.lang.Exception: ReaderError:(3,1) EOF while reading

Hi Joubert,
This is probably the most common "gotcha" in Clojure. I think anyone
who uses Clojure writes this kind of bug sooner or later. :)

Was the 'other side' (Berkely DB) in a separate process / machine? Or
part of the same jvm?
If separate, what clojure knowledge / libraries did the other side
have? I assume there was serialization across or else you wouldnt have
gotten the PersistentMap error.
And sounds like your passing the CLA
