Hi All,
I have a question regarding ambiguity in reflective dynamic invocation.
In Clojure you can dynamically invoke a method on a Java class like so:
(. some-instance bar arg)
where bar is a method name.
If the type inferencer can't ascertain the type of some-instance a runtime
reflective p
ing method if several are found.

If the head is retained on a lazy sequence we have a potential memory leak.
I set my JVM memory low, 64mb and ran the following:

#'user/test1
user> (test1 (take 1000 (iterate inc 0)))
499500

Now if we do:

Hi,
I'm transforming a recursive form structure to an equivalent structure
represented by Clojure records. I want polymorphic dispatch across my newly
created structure of records. I also want to be able to apply a function to
transform the structure of records, in much the same way as say
clo
I found a bug in Clojure core, and know its solution, question is how
to submit a bug report?
FYI here is the bug:
=> (.withMeta list {:a 1})

This is reporducable in Clojure 1.2 and Clojure 1.3
This cause of this issue is in:

If I remember rightly I solved this by binding *ns* before the eval, e.g.
(binding [*ns* some-namespace]
(eval form))

Hi All,
One of my first posts to Clojure mailing list. I had an idea around SCMs
and Clojure. I'd basically like to put the idea out there and get some
feedback. I hope I'm not breaking any etiquette linking to my blog post but
I've outlined the idea here:

Hi, stumbled on a nasty bug in Clojure. I'm transferring Clojure objects
around using java serialization. When de-serializing a List
(clojure.lang.ASeq) it has a hashCode of 0. This means lookups for the
object in HashMaps PersistentHashMaps HashSets etc fail. The pre-serialized
version of the
I don't think that's a realistic option for me. I have java objects
embedded in the Clojure forms, and the graph is pretty big.

Hi All,
Does anyone know of a good simple library to call/consume web-services from
Clojure? Note I don't want to create a web-service just call one.

I have unexplained behavior for with-meta.
As far as I understand with-meta should not alter object identity. E.g. if
we have the (= a b) => true for some a and b then
(= (with-meta a ma) (with-meta b mb)) => true should also hold for any ma
and mb.
So why do I get the following behavior at th
Hi Clojure Group,
I'm new to the group, apologies if this topic has been raised before.
Basically I'm wondering if there is a reason why the form used to
defined a function isn't attached as meta-data to the function.
Clojure is a isomorphic language and this capability would really help
me out wi

I hit the following error today. My environment is Clojure 1.3

Ok not to worry, my environment was bust, a repl restart sorted the
issue.
