If I add an @ it runs:

Jeff Brown has released a clojure plugin for grails.

So you can now write clojure code in grails app.

Typically, I think so. You could also use multimethods, but that might
be unnecessary flexibility.
Another approach is to emulate keyword arguments:

Hi all,
in my quest to learn clojure (and lisp in general), I'm currently
trying to translate some the "On Lisp" code to clojure.
The first couple of functions and macros in Chapter 19 "A Query
Compiler" read:
(defun make-db (&optional (size 100))
(make-hash-table :size size))
(defvar *defau
As I said, the example was stripped down for simplicity, and that
simple version doesn't make much sense other than for communicating my
problem.
My real val-fn is not a map, it's indeed a couple of functions,
applied to some data that's passed in. But the result of that acts
like a map: it retur

I haven't had your exact problem, but sometimes it seems to
incorrectly maintain depth at the top level, so I'll end up with
something like
(defn foo [x y]
...)
(defn bar [a]
...)
(defn baz [...]
...)

Yes. But val-fn might also be exactly that: a function

a map. I'm not su

Hi, Tim,
I'm not 100% certain what is going on here, but I do know that, in
general, binding and loop/recur should not be mixed.
"recur" is not true recursion -- it's more like a GOTO. The "binding"
macro establishes thread-local bindings using the static methods
