Re: Allow Data Structure to Be Called as Function

[Michael Nygard]

You could also use reify:

(defn make-foo [s] 
  (reify clojure.lang.IFn 
(invoke [this] (str Hello,  s

((make-foo RJ))
Hello, RJ

I have to admit, though, that I'm unclear on the relative merits of defrecord 
vs. reify. Anyone want to comment?

Cheers,
-Michael Nygard

 Hi,
 
 I'm sorry if this has been asked before, but I would like to know how
 to create data structures in Clojure that can be used in the same way
 as the built-in data structures.  For example, I can access the
 elements of a vector by (my-vec 1).  How can I implement this
 interface when creating a data structure in Clojure?
 
 (defrecord Foo [...]
  ...
  IFn
  (invoke [this] (do-this-on-zero-argument-call))
  (invoke [this x] (do-when-called-with-x))
  (invoke [this x y] (+ x y)))
 
 = ((Foo.) 33 9)
