cadr etc ...

would it be possible to have a function somthing like
(indexof i l), where i is the index and l is the list and instead of it returning the index it return the car position of it?

for example, (indexof 2 l) would evaluate to (cadr l)

Yes

>>1
car position

What the fuck learn to proper Lisp names.

>>1
I don't think CADR does what you want, unless you're just looking to rewrite NTH.

(defmacro consn (n list)
  `(,(read-from-string
      (concatenate 'string
           "ca"
           (make-string n :initial-element #\d)
           "r"))
     ,list))
