Interesting situation in clojure
So I was trying to do something like this:
(defn bad-function [body]
(let [result “hello”]
body))
And then I tried to do something like this:
(bad-function (println result))
And it failed. I didn’t understand why it would failed since I do something very similar in our regular non-lisp languages.
I don’t fully understand what is the problem, but this is my guess: when the reader begins to apply (bad-function (println result)), it wants to apply the body at some point before the result binding happens.
I believe that if I am going to be able to do something like that, I am going to have to use macros.
I would like to know what exactly is going on though.

the problem is that the body is evaluated before being passed to the function. you want macros as an example (defn oh-no...
