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.

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

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

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?

Hi,
I'm afraid I'm new to Clojure, so I'm not even going to attempt a

The stacktrace is below, if anyone's interested.
