user=> (read-string "#(%)")
(fn* [p1__3#] (p1__3#))

... that's why the error in question sort of boils down to "7 can't be called as a function"

Thanks! Good to know about read-string for the future

(#(do %) 7) ;> 7

Also if you wonder why #() works this way, it's supposed to be a feature, it prevents double parentheses in many case like:

(filter #(= 1 %) ...)

(filter (fn [x] (= 1 x)) ...)

Same basic idea, but I tend to prefer -> to do for these cases: #(-> %).

sometimes I wonder why (defn id [x] x) isn't in core

@noisesmith Isn't that identity ? https://clojuredocs.org/clojure.core/identity

Do has other advantages, like: #(do (println %) %) 🤣

that's doto. anyway, I don't hate do, I just think preferring #(do %) over a well named core function is silly.

I don't know, id seems a bit of a confusing name. But I understand the feeling

Hmmm, I've used languages with id for identity.

Fair, you'd just know, but I first read it as "id" in the sense of identifier 😛

it's 'id' as in the unknowable indescribable thing that lives under the surface of ego

(german for "it")
