Proper use of function form

[Tim Johnson <tim@akwebsoft.com>]

Here is a key definition:

(define-key jinja2-mode-map (kbd "C-c i") #'jinja2-insert-var)

As I understand it, the sharp-quote (#') tells the compiler that 
jinja2-insert-var is meant to be a function

The following quotation:

"it is always good practice to sharp quote every symbol that is the name 
of a function, whether it's going into a |mapcar|, an |apply|, a 
|funcall|, or anything else."

Can be found at 
https://endlessparentheses.com/get-in-the-habit-of-using-sharp-quote.html

fuurther text there describes the special 'function form for which the 
sharp-quote is a shorthand.

Suppose we are processing a sexp of alternating strings and symbols:

(setq my-keypairs '("h" my-h-func "g" my-g-func "f" my-f-func))

and using iteration to *programmatically* call define-key for multiple 
key definitions as in

(define-key mymap                               ;; add to keymap
     (kbd (concat ldr (nth ndx mylist)))    ;; sequence as in "g"
     (nth (+ ndx 1) mylist))                      ;; command as in my-g-func

The form above is indeed a snippet from a defun that I have used for years

Would it be better to change (nth (+ ndx 1) mylist) to (function (nth (+ 
ndx 1) mylist)) ?

I note that help for 'function states a preference for using it with 
function objects, but says nothing about processing a list. Hence I am 
lobbying wiser heads than mine for opinions before I implement something 
that might cause subtle problems down the road.
