Checking out clojure.core/destructure and clojure.core/let might be
helpful.
Here's a macro I hacked together. It doesn't work with :keys, :as,
or :or. I take no responsibility if you use it for anything real. But
maybe it will provide you with some ideas.

Thank you, Alex, for the response and your work on the code. And

Hey all,
So, for a random project, I found myself using a single protocol
extended to a bunch of record types. I did this using the support
in `defrecord` itself, but what I dislike about it is that the
definitions for each method of the protocol are spread out amongst
multiple sections of code.
Hi All,
Just released v0.2.2 of HTTP Asynchronous Client.
Featuring following changelog http://bit.ly/hc9dxt
- get-encoding helper works w/o Content-Type header
- upgrade async-http-client to v1.5.0
- exposed more configuration options
- zero byte copy mode
- allow providing your own poll

I have a library called Evalive (http://github.com/fogus/evalive) that
could help. Specifically I added a macro named `destro` that will do
_mostly_ what you want. Basically, it looks like the following:
(destro [a b [c d e]] [1 2 [3 4 5 6 7 8]])
Which returns:
{vec__2183 [1 2 [3 4 5 6 7
Can't you just use extend-protocol to group your protocol
implementations for each record type in one place?

Sorry, I wasn't being very clear about my needs.
I need this function to run at *run-time*.
So the following:
(def values [1 2 [3 4 5 6 7 8]])
(def form '(a b (c d e)))
(destructure form values)
Should return:
{:a 1 :b 2 :c 3 :d 4 :e [5 6 7 8]}
I was wondering whether the destructure function

Your answer isn't that ugly. It's very similar to what I have as

I would like to know if you think it's possible to re-use let to do
this. I feel like I'm re-inventing the wheel somewhat.

how to avoid repeating the same thing twice (once in function world

Yes, I would like to replace Java version with Clojure. For the

Do you mind elaborating a little bit on the functions? Your help is greatly

Is the following behavior correct or a bug:
user (defrecord Example [data] clojure.lang.IFn (invoke [this] this)
(invoke [this n] (repeat n this)))
user.Example
user (def e (Example. I am e))
#'user/e
user e
#:user.Example{:data I am e}
user (e 2)
(#:user.Example{:data I am e}
Thanks for the reply Ken.
While the macro is executing body will be bound to an
s-expression (basically, source code parsed to an AST but no further;
source code as processed by the reader).
This is the part where it falls apart. body is actually bound to a
single symbol.
For example in the
