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

around that? Ha
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.
Sincerely

Since the sorting is stable (relative order is kept), we know that the first
occurrence of each id is either the existing map from data1, or the new map
from data2.

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:

However, given the situation I think

The important part were that the "dosync" call is isolated. The condition
doesn't really matter.
By the way: wouldn't it be simpler to create a new map instead of altering
unique-offers/all-offers?

A more foolproof way might be to use a macro, but then macros have

It depends on what clj123123 wants to us
see if the elisp exists, like so:

sldb-line-bp
see if the keymap exists like so:
M-x describe-value
