One more thing…
If I try this, it looks okay

But within the function, I get cast exceptions.

You have to manage resources at a larger scope that encompasses all your use
of the lazy sequence. The quick-and-dirty solution is to use `doall` ins
clojure.contrib.json (or the new clojure.data.json) has an option to *not*

Probably does what you want.

hi,
I have 2 report files in JSON format like below:
# file 1: a.json
{ "abcdef" : { "value" : "10" }
# file 2: b.json
{ "abcdef" : { "value" : "20" }
I am using clojure.contrib.json to read each file, and I want a
function that takes in the 2 structures and a metric name (e.g.
abcdef). The fu

Hola,
I'm looking for a function that updates a map value by calling a
function on it.
(def foo {:a 1})
So instead of this:
(assoc foo :a (inc (:a foo))); => {:a 2}
Something like this:
(map-fn foo :a inc); => {:a 2}
Does that exist somewhere, or should

Except in 1.3 it will be a little bit harder to do "throw-away" per-thread
memoizes for vars you do no "own" if their author didn't make their holding
