I've been playing with making a macro to encapsulate Stuart's post, like
this:
(defmacro defrecord-ifn [name & args]
`(defrecord ~name ~...@args
clojure.lang.IFn
(invoke [this key] (get this key))))
(defrecord-ifn Foo [a b c])
(def foo (Foo. "A" "B" "C"))
(prn (map foo [:a :c])) => ("A", "C")
I get the error:
"No such var: user/this". I guess this is because it is expanding 'this' to
'user/this'. What is the proper way to get a macro like this to expand
properly?
