Turns out my problems were due to AOT compiling. Doing `lein clean` before
firing up the repl fixed things.

Dear group,
I have the following use case: I have a socket connection to an external
service. I want several threads to use the same connection.
Importantly, in order to get a synchronized response from the external
service, every write must be followed by a read before another write is
my two cents:
The extra readability to users when using keyword args also comes from the
fact that a function's options are explicit in its signature. So during
development, instead of having to look them up in the docs or in the code,
my emacs mini-buffer simply shows them to me. Although I
Got it! :-)
One more thing. While developing, I often have to deal with large amounts
of data that take quite a while to load. However, the data is lost and so
has to be reloaded after every reset, which is a bit annoying. Is there a
way to prevent this?

system map and starts a thread

Hi Malcolm,
I have a follow up question if you don't mind. Suppose I want to define a
component that starts a thread and regularly checks a resource. If the
resource changes, this has repercussions for other (dependent)
components. How would you do that in jig?
Maybe this question is too

I was thinking of letting components not only implement the Lifecycle

I just realized that another approach would be to hold the jdbc connection

Hi List,
As documented at http://clojure.org/reader, defining a record with

(ns test)

= test.X{:a :foo, :b :bar}
However, the record reader form does not seem to be visible

seems a bit overkill?
