as an aside, if you're writing def-like macros, I'd encourage you to
look at 'clojure.tools.macro/name-with-attributes'

Hi!
I want to use reify in macro, but the namespace is the problem. the
following code shows what have done. is there a way to make it right?
Probably this will work:
(defmacro def-site-entity
[ent & body]
`(let [e# (create-e)]
(def ~ent (reify ~'clojure.lang.ILookup
(valAt [key# not-found#]
(condp = key#
:db (deref ~'t1)
:options (deref ~'t2)
(get e# key# not-found#)))))))
Basically, every symbol that shouldn't be qualified but should appear as
written in the macro definition has to be prefixed with ~'. I think you
could also write ~'@t1 instead of the more verbose form (deref ~'t1) but
I wasn't sure.
Bye,
Tassilo
