cond. I often do a couple of tests, then would like to lock down some
symbols that I'll use frequently in the remaining cases.
There's a precedent for this, in that the for macro allows a :let as
an alternative to a list
Coming right up!

So you have a working version of this macro, as well as some use cases
in actual code? This would help the discussion a lot.
Thanks!

Here's my implementation. Seems to be working fine. I like it.

Just had a bit of a gotcha on Clojure that I thought I'd share.
My tests started hanging after completion, which was a real pain on
the continuous integration server.
After some investigation, I determine that this unwanted behavior
started when I first introduced agents into my code.
I needed
I like to try and keep my level of nesting under control, and this
often involves hiding or re-structuring the let macro. The for macro
can implicitly assemble a let macro for you, but with a limitation
that the :let clause can't be first:
1:5 user= (for [:let [z [:foo :bar]] x z] (name x))
From my perspective, having the forms be flatter (less nested) and
having the call to the extend-dom function be at the outermost level
is the most readable.

When I first looked at Clojure, I didn't get it (I scanned the docs
for 10 - 15 minutes). A few month later, Stu Halloway said to give it
a second look and boy am I glad I did. Go read Stu's book, or at least
the first couple of chapters online at Manning. Digest for a bit.

It looks very nice ... still I'd love to see something like what
clj-doc does (http://github.com/mmcgrana/clj-doc) ... it adds a text
field that you can type into and it matches the available names
against what you type, hiding the rest. So if you know part of the
name, you can take a very large
Symbols are late resolved to functions.
(def t (fn ...)) means define a Var bound to symbol t, and store the
function in it. In JVM terms, the function becomes a new class that is
instantiated.
(t (dec x)) means locate the Var bound to symbol t -- at execution
time (not compilation time) ---
