Support arbitrary functional destructuring, that is the use ofany function in any destructuring form to help unpack data inarbitrary ways.
The discussion began here:http://clojure-log.n01se.net/date/2009-11-17.html#09:31c
The attached patch implements the spec described here:http://clojure-log.n01se.net/date/2009-11-17.html#10:50a
That is, the following examples would now work:
user=> (let [(-> str a) 1] a)"1"
user=> (let [[a (-> str b) c] [1 2]] (list a b c))(1 "2" nil)
user=> (let [(->> (map int) [a b]) "ab"] (list a b))(97 98)
