You are using macroexpand wrong. Don't eval anything when you are

G'day folks,
I've recently started using defnk more widely, and just run into the
fact that pre and post conditions won't work. I understand that this
is because they are a clojure special form and therefore cannot be
supported by the macro - is that right? Is there any way to work
around that?
Hi,
clojure supports keyword arguments for a quote some time now.
(defn foo
[positional1 ... positionalN {:keys [kw1 ... kwn]}]
...)
The syntax is the usual destructuring syntax for maps. So you can specify
defaults via :or etc. And even have none keyword keys.

Ok. But whether it's reasonable or not, it can happen. For example,
the project I work on can't be located in a Windows folder deeper than
37 chars long because Swig generates a particularly long Java file. It

Hi,
I use cond in dosync but it doesn't work. Here is a function code:

unique-offers (:unique-offers args)

However, given the situation I think
(cond

:else (logger/log error))
