ok you're right, it's impossible to get the var since those x and y are
already resolved to the function, and multiple vars could point to the same
function anyway.
=> (let [x assoc
y x]
(get-lexical-env)
)
{x #<core$assoc clojure.core$assoc@35fcd90c>, y #<core$assoc
clojure.core$assoc@35fcd90c>}
for consistency, ignore the following:
;the following is inspired from
http://blog.jayfields.com/2011/02/clojure-and.html
(defmacro get-lexical-env []
"
=> (let [a 1 b (+ 1 2)]
(let [c (do \"a\" \"b\")]
(q/get-lexical-env)
)
)
{a 1, b 3, c \"b\"}
"
(let [envkeys (keys &env)]
`(zipmap (quote ~envkeys) (list ~@envkeys))
)
)
(defmacro show-lexical-env []
`(clojure.pprint/pprint (get-lexical-env))
)
