You have to use apply. (apply print-value-a [:b 7 :a 3]).
Furthermore: how could (let [{a :a} [:b 7 :a 3]] [a]) possibly work?
Vectors are indexed by integers.
user=> (let [{a :a} [:b 7 :a 3]] [a])
[nil]

There are parallels to 'hash-map' and 'sorted-map' in the api:
user=> (hash-set :a :b :c)
#{:a :c :b}

This Q came up on the Leiningen list but I wanted to share my answer
on the larger Clojure group to get feedback from a bigger pool...

This question is a bit abstruse, so please bear with me :-)
Here is an example of a function with named arguments and default
values from the book "The Joy of Clojure". It uses optional arguments
(via &) and map destructuring.
(defn slope
[& {:keys [p1 p2] :or {p1 [0 0] p2 [1 1]}}]

Thanks for these applications to look at. These look nice, but don't have
much use for STM.
Do you know of any applications that make a lot of use of Software
Transactional Memory?

Ok, I've got a simple web application that works running on embedded
jetty using the ring jetty adapter. I would now like to deploy it in
an infrastructure that will restart it if it dies, the system reboots,
etc. I've already got tomcat doing most of that, so the obvious choice
is a WAR file. Trou

Good stuff. The ivy branch of cake has something similar but only
works at the dependency module level (not the namespace level).

Yours is better since it would give us a visual representation of the
namespaces..

Hi,
your code is really hard to understand. Please let let to be your
friend! I extracted things a little bit and put everything in a let.
Since I have no clue about collission detection in physics engines I
derived the local names from the operations done "i"nc, "d"ec, etc.
