A point worth making is that Riak is a dynamo based kv store. Which, most

Hi,
It turns out that c.c.json/json-str will spit out Ratio's in a manner which
is not json compliant.
(json-str [3/4])
=> "[3/4]"
This parses correctly in the reverse situation:
(read-json (json-str [3/4]))
=> [3/4]
When being read [1] we switch over to using the clojure form reader so this

Hi Guys,
One of the things that has struck me about clojure, by virtue of being
a lisp, is the concision of the code - I really find it very
attractive. However yesterday I found something that I couldn't work
out how to do in a concise manner. Clearly commenting the code was a
priority once I got
