Hi Erlis,
Just to confirm: there currently aren't any built-in tracing or other
special debugging capabilities in clooj. tools.trace is quite cool, though.

I'm using clojure.contrib.json library, and I might encounter a bug of

The bug occurs when I use json-str to a map which contains double

is my expected behavior):

That does feel a bit more natural, but how would you handle :keys, :as, and :or?

read/pr-str works well, but it's painfully slow relative to something
like Redis. JSON libraries and the like would be faster, but might
require more contortions if you're using lots of Clojure data types.

serialization library
I had the same thought when I first started learning Clojure - I think
the idea is that there is some nice mental resonance when
destructuring matches up to your mental model of the data structure

Here's an example of a Ring session store that writes clojure maps to and

Thanks for your response Benjamin. I was leaning towards cyclic
dependency myself. I couldn't get closurebuilder.py (which apparently
detects cyclic dependencies) but couldn't get it to run on my source.
After your response, I did a dependency analysis by hand and found no
cycles. However, I
It might be an idea to figure out some standard syntax we could use,
like Markdown, that could be used for formatting docstrings.
My vote is for Markdown as well.

That works - thanks.
Still, it seems intuitive to build the code as I had originally done.
It's too bad code has to get complicated so quickly :)
Thank again for the help.
