The problem is in embedding an actual function object instead of a
form which creates the function object. That results in a form which
can't be read properly and thus the cryptic error.

True. Thanks for confirming this.

Seems like the expansion is trying to put the function's value in there,
and this has already been compiled. If the function' code is expanded
in-place it works.

This macroexpansion looks fine to me... but still gives an error when you
try to call (bar alex).

I appreciate you chimed in, though the mention of your name was purely
coincidental. :)

Hi Shantanu,
I had to play with this because it seemed like for some reason you were
trying to call it on my name :)
So far one thing I've isolated is that if you cut out the function calls it
will compile the macro:
(defmacro bar
[a]
(let [b (keyword a)
f (fn [& args] b)]

Hi,
I am running into error when using macros with deftype. For example,
when I use the macro `foo` it works fine:
(defmacro foo
[a]
(let [b (keyword a)]
`(do ~b)))
(foo alex)
=> :b
whereas, when I use the macro `bar`:
(defmacro bar
[a]
(let [b (keyword a)
f (fn [& args] b)]
