I'm assuming the StackOverflow link you refer to is
http://stackoverflow.com/questions/3259825/trouble-with-lazy-convolution-fn-in-clojure.
I would think about the problem this way: to compute the value at index i in
the output list, you multiply together each pair of values in the input lists
Where's the link? :)

Congrats on the 1.2 beta guys!
When I AOT a defrecord it does not javaize the clojure namespace into
a proper java package name.
(ns this-that)
(defrecord Fred [])
;creates a class file
this-that.Fred.class
Is this by design? What is the thinking here?

This is an instance of the broader issue whereby records currently
evaluate to maps. There was a ticket open for that on Assembla. I'm
not sure what's the current status on that, but whenever it gets
fixed, macros will be able to use records in their expansions.

Hi Nicolas,
I get the idea, but I don't see how this would help provide a default
implementation for the functions inside a protocol. It looks to me
like this would be the same as creating a record with only some of the
functions implemented. Or am I reading it wrong?
Thanks for your input.

Rick,
I think the problem is that additional classpaths are added,
dynamically, after the user.clj file is evaluated. It does get
evaluated if it's in ./ or ./src, which are added at launch in the
cljr scripts.
I have added ~/.cljr to the classpath defined in the launch scripts,
so you can place
I read my mail and couldn't understand it.
Here is what I meant:

(message-received ...))
(defprotocol ExceptionCaught
.)
(extend Object MessageReceved {:message-received
default-message-received-function}...
)
(deftype channel-handler
ExceptionCaught
Not very clean suggestion.
Split the protocol in one protocol per function.
Instance every one on Object, with the default protocol.
Instance each specific on the function for which it has a special instance.

Hi all,
I am writing a network protocol handler based on events (to wrap

Hi Stefan,
The behavior you are seeing is not a problem, and understanding why may be
helpful to using agents correctly.
The thread that sends to an agent has no guarantee that it will (or will not)
see the result of its action a tiny bit later, when the repl prints the
stringified version of
This behavior is by design.
(1) The absence of warning is consistent with proxy, reify, etc. You specify as
much as you want, and there is no warning. This is very unlikely to change!
(2) The dynamism implied by a hypothetical "append-partial-protocol" seems high
on complexity and low on value

It's better to illustrate this with simple example:
If I'll define following protocol:
(defprotocol test1
(a1 [this] "a1")
(a2 [this] "a2")
(a3 [this] "a3")
)
and then I can extend it with following constuction:

Hi,
I think I found a minor problem. It appears with the error handling
of agents and actually is just a minor glitch in the output.
Consider the following session, copied from a terminal:

With time, your REPL will start slower and slower and slower though.
