Hello everybody,
I really like the &env. It has saved a lot of tedious work a couple of times
.. but I have only found use for the keys of the map that gets passed like
in the following example.
(defmacro display-local-bindings []
`(do ~@(map (fn [x#] (list 'println [`'~x# x#])) (keys &env))))
(let [x 10
y 20]
(display-local-bindings))
would print
[x 10]
[y 20]
I don't understand what the val part of the map contains? I have failed at
attempts to figuring it out.. Can somebody tell me what the val part
contains and how one could use it?
Thanks,
Sunil.
