I see that you can pass extra args to `apply` --- between the func and the
coll args --- and `apply` will prepend the extras to the coll before
proceeding. For example, these all work:
(apply + [1 2 3 4])
(apply + 1 2 [3 4])
(apply + 1 2 '(3 4))
While thinking about how the following works:
~~~
(apply map vector [[:a :b :c]
[:i :j :k]
[:x :y :z]])
~~~
I found this:
~~~
some-app.core=> (apply map [vector [:a :b :c] [:i :j :k] [:x :y :z]])
([:a :i :x] [:b :j :y] [:c :k :z])
some-app.core=> (apply map '(vector [:a :b :c] [:i :j :k] [:x :y :z]))
ArityException Wrong number of args (3) passed to: Symbol
clojure.lang.AFn.throwArity (AFn.java:429)
~~~
Why does it fail when I pass a list there instead of a vector?
