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)]
`(deftype ~b []
clojure.lang.ILookup
(valAt [this# k#] )
(valAt [this# k# d#] ))))
user=> (bar alex)
user.alex
