George, I don't know what time zone you live in, but you are one crazy
person!
I'm on vacation in NYC for a couple more days, then back home to
Silicon Valley. Still jet lagged which explains my odd hours. (Not
to mention that being in New York is such a rush it's pretty hard to
sleep!)
I want to define and use a map that is private to a namespace and used
by several functions in that namespace. Is the idiomatic way simply
to def it within the namespace? Is there another way to hide it?

So I would say: Unqualified symbols in the namespace the def happened
in will resolve to the def'd Var. (of course only after the def

so in theory one could have a symbol foo bound to a var bar?

I guess this means there's no var named user/foo and hence the symbol
cannot get its closest match in name?
Hi,
or a maybe clearer example, which shows the different states:
; No Var, yet.
user= (var foo)
java.lang.Exception: Unable to resolve var: foo in this context
(NO_SOURCE_FILE:1)
; Var is now defined. Hence it can be resolved. But it has to root

Hi,
I'm afraid I'm new to Clojure, so I'm not even going to attempt a
patch, but I get a NullPointerException when I pass an empty map
(e.g., {} or {:something {}}) to lazy-xml/emit.
The stacktrace is below, if anyone's interested.

Hope, that helps.
It does indeed.
So, def either creates or looks up a var of the name of the symbol
given and then every time eval comes across a symbol it tries to
lookup a var of the same name?
(just read http://clojure.org/special_forms#def which I should've read
before posting)

Well, taking a brief look over your code, it seems like the main
difference is that scriptjure is macro-based, so all the code generation
gets done at compile-time.
That makes scriptjure faster, but at the expense of needing an unquote

A bit shorter than writing the meta-data by hand.
Def provides a number of other interesting shortcuts. Have a look at

It's fairly common to let over a function, e.g.:
(let [a (atom 0)]
(defn next-id []
(swap! a inc)))
In the above, the atom can only be referenced from within the lexical
scope of the let, hence essentially private to the next-id function.

I confess I'm a bit baffled by this too, but I have a couple
suggestions that don't address your problem :)
(drop 2 (range)) is the same as (iterate inc 2), and the same as your
convoluted lazy-seq, except that the iterate works here, while for
some reason the range doesn't.

When a var's definition has a lazy reference to itself, as primes does below,
then your results will be dependent on the lazy/chunky/strict-ness of the calls
leading to the lazy reference.
The functions range, rest, and remove are chunk-aware, so the range-based
version of primes consumes a
