I ended up using (list ~@attrs) which is very similar to what you're
suggesting...:)

~(vec attrs), perhaps?

HI all,
I've gotten myself into a weird situation...
I'm defining a def-like macro and I want to use
'name-with-attributes'. Consider the following skeleton:
(defmacro defX [name & args]
(let [[name attrs] (name-with-attributes name args)]
`(let [cs-coll# ~attrs]
(assert (every? component? cs-coll#) "Can only accept IComponents")
(def ~name (Workflow. cs-coll# {:description (-> ~name meta
:doc)} nil)))
now consider that I am calling this like so:
(defworkflow my-stem-pipe "my own basic stemming pipe" my-ssplit
my-tokenizer porter-stemmer)
where the last three symbols refer to records which implement IFn...
doing "~attrs" tries to invoke the list as a function-call because
the first symbol happens to be a function but I just want the list
of records (eval'd symbols) so the assertion can proceed...
any ideas?
Jim
