For what it's worth, I found that working with complex numbers in
clojure doesn't require specialist types or notation at all:

Hi everybody,
I've implemented a very simple job distribution service:
http://github.com/schani/clj-simple-dist
It's based on RMI, so it requires Clojure 1.2 to serialize Clojure
data. It's (supposed to be) fault-tolerant, very simple to set up and
even has a little web interface that
